No input/output.
This wraps [[NS_Services|ns]] LaunchSystemApplet, ignoring the u64 returned by that cmd (and other functionality).
==== LaunchStarter ====
No input/output.
This is similar to [[#LaunchSystemApplet]], except this uses [[NS_Services|ns]] LaunchLibraryApplet with a ProgramId from global state.
The global state field is initialized elsewhere with the value of [[System_Settings|system-setting]] <code>am.debug!starter_id</code>, defaulting to ProgramId 0100000000001012 ([[Title_list|starter]]) if not available.

ReadThemeStorage/WriteThemeStorage: these commands copy data from/to a state buffer and the user specified buffer. The size of the state buffer is 0x400-bytes. The default content of the ThemeStorage prior to using the WriteThemeStorage cmd, is: <code>memset(statebuf, 0xAA, 0x400);</code>
 
=== ReadThemeStorage ===
Takes an input u64 '''offset''' and a type-0x22 output buffer, returns an output u64 '''actual_transfer_size'''.
 
=== WriteThemeStorage ===
Takes an input u64 '''offset''' and a type-0x21 input buffer, no output.
 
=== PushToAppletBoundChannel ===
Takes an input [[#IStorage]], no output.
 
This is similar to [[#PushToAppletBoundChannelForDebug]] (no DebugMode check), except the used s32 is loaded from elsewhere and must be in the range 31-32.
 
=== TryPopFromAppletBoundChannel ===
No input, returns an output [[#IStorage]].
 
This is similar to [[#TryPopFromAppletBoundChannelForDebug]] (no DebugMode check), except the used s32 is loaded from elsewhere and must be in the range 31-32.
 
=== GetDisplayLogicalResolution ===
No input, returns an output s32 '''width''' and s32 '''height'''.
 
=== SetDisplayMagnification ===
Takes an input float '''x''', float '''y''', float '''width''', and float '''height''', no output.
 
Sets the DisplayMagnification. This is essentially layer image crop, for everything non-Overlay.
 
'''x''' and '''width''' are multiplied with the same width value returned by [[#GetDisplayLogicalResolution]], so these should be in the range 0.0f-1.0f. Likewise for y and height, except these are multipled with the height value.
 
=== SetHomeButtonDoubleClickEnabled ===
Takes an input u8 bool, no output.
 
=== GetHomeButtonDoubleClickEnabled ===
No input, returns an output u8 bool.
 
=== IsHomeButtonShortPressedBlocked ===
No input, returns an output u8 bool.

The BOTW game uses this GamePlayRecording functionality from the main-nso "nninitStartup" function, with size 0x6000000(96MiB). The official GamePlayRecording-enable code does the following(this will panic on any failure):
==== GetMainAppletApplicationDesiredLanguage ====
* [[SVC|Creates]] TransferMemory using the input buffer and size, with permissions=0.
No input, returns an output [[Settings_services#LanguageCode|LanguageCode]].
* Uses [[#InitializeGamePlayRecording]] with the TransferMemory.
* Closes the TransferMemory handle, + TransferMemory cleanup.
* Uses [[#SetGamePlayRecordingState]] with value 0x1.
This GamePlayRecording functionality presumably enables the video-recording usable starting with [[4.0.0]].


==== PopLaunchParameter ====
==== GetCurrentApplicationId ====
Takes an input u32 [[#LaunchParameterKind]], returns an output [[#IStorage]].
No input, returns an output [[NCM_services#ApplicationId|ApplicationId]].


Pops a LaunchParameter [[#IStorage]], the storage will be removed from sysmodule state during this.
Gets the [[NCM_services#ApplicationId|ApplicationId]] for the currently running Application. ApplicationId=0 when no Application is running.


==== CreateApplicationAndPushAndRequestToStart ====
==== RequestExitToSelf ====
Takes an input [[NCM_services#ApplicationId|ApplicationId]] and an input [[#IStorage]], no output. ApplicationId=0 can be used to relaunch the current application.
No input/output.


==== CreateApplicationAndPushAndRequestToStartForQuest ====
Same as [[#RequestExit]] except this is for the current applet.
Takes 2 input u32s (loaded from struct [[#ApplicationAttributeForQuest]]), an input [[NCM_services#ApplicationId|ApplicationId]], and an input [[#IStorage]], no output.


==== CreateApplicationAndRequestToStart ====
==== CreateApplicationAndPushAndRequestToLaunch ====
Takes an input [[NCM_services#ApplicationId|ApplicationId]], no output.
Takes an input [[NCM_services#ApplicationId|ApplicationId]] and an input #IStorage, no output.


Same as [[#CreateApplicationAndPushAndRequestToStart]] except without the input storage, official sw uses this when no input storage is specified.
This is is similar to [[#CreateApplicationAndPushAndRequestToStart]].


==== CreateApplicationAndRequestToStartForQuest ====
==== CreateGameMovieTrimmer ====
Takes 2 input u32s (loaded from struct [[#ApplicationAttributeForQuest]]) and an input [[NCM_services#ApplicationId|ApplicationId]], no output.
Takes an input u64 size and a TransferMemory handle, returns a GRC [[GRC_services#IGameMovieTrimmer|IGameMovieTrimmer]].


Same as [[#CreateApplicationAndPushAndRequestToStartForQuest]] except without the input storage, official sw uses this when no input storage is specified.
This is a wrapper for GRC [[GRC_services#OpenGameMovieTrimmer|OpenGameMovieTrimmer]].


==== CreateApplicationWithAttributeAndPushAndRequestToStartForQuest ====
Official sw uses an user-buffer for the tmem, with permissions=0.
Takes an input [[NCM_services#ApplicationId|ApplicationId]], a type-0x15 input buffer containing an [[#ApplicationAttribute]], an input [[#IStorage]], no output.


Same as [[#CreateApplicationAndPushAndRequestToStartForQuest]] except the entire attributes structure is directly specified via the input buffer. This command replaces [[#CreateApplicationAndPushAndRequestToStartForQuest]], official user-processes no longer use [[#CreateApplicationAndPushAndRequestToStartForQuest]].
==== ReserveResourceForMovieOperation ====
No input/output.


==== CreateApplicationWithAttributeAndRequestToStartForQuest ====
Updates state fields. This must be used before [[#CreateGameMovieTrimmer]].
Takes an input [[NCM_services#ApplicationId|ApplicationId]] and a type-0x15 input buffer containing an [[#ApplicationAttribute]], no output.


Same as [[#CreateApplicationAndRequestToStartForQuest]] except the entire attributes structure is directly specified via the input buffer. This command replaces [[#CreateApplicationAndRequestToStartForQuest]], official user-processes no longer use [[#CreateApplicationAndPushAndRequestToStartForQuest]].
==== UnreserveResourceForMovieOperation ====
No input/output.


==== EnsureSaveData ====
Updates state fields. This must be used once finished with [[GRC_services#IGameMovieTrimmer|IGameMovieTrimmer]].
Takes an input u128 userID, returns an output u64 size.


Calls sdk func <code>nn::fs::EnsureApplicationSaveData</code>. [[qlaunch]] also calls this same sdk func directly.
==== GetMainAppletAvailableUsers ====
Takes a type-0x6 output buffer containing an array of u128 userIDs, returns an output u8 bool and a s32 '''total_entries'''.


Creates the various savedata as specified by the application [[NACP_Format|control.nacp]] when the savedata doesn't exist.
This gets the userIDs previously set by [[#SetUsers]].


Official user-processes launch the dataErase LibraryApplet depending on the Result, the above output size is used with this.
The size of the output buffer in entries must be at least 8.


==== GetDesiredLanguage ====
Normally the output bool is set to 0, however when no users are available it's set to 1 with '''total_entries''' = -1.
No input, returns an output [[Settings_services#LanguageCode|LanguageCode]].


==== SetTerminateResult ====
==== SetApplicationMemoryReservation ====
Takes an input u32 '''Result''', no output.
Takes an input u64, no output.


For example, in some cases official apps use this with [[Error_codes|error]] 0x2A2 then uses svcBreak.
An Application must be currently running. The input u64 must be 0x1000-byte aligned.


==== GetDisplayVersion ====
==== ShouldSetGpuTimeSliceManually ====
No input, returns an output 0x10-byte struct.
No input, returns an output u8 bool.

This is exposed by sdknso under <code>nn::friends::</code>. When the storage_size is <0x10, this returns false. <code>data_size = storage_size-0x10;</code> Then the first 0x10-bytes from storage are read to stack, which is later copied to the output Uid on success prior to returning. Then the storage is read into the specified output buffer with storage-offset 0x10, where the size is <code>size = data_size > buf_size ? buf_size : data_size</code>. Reading is skipped if size is zero. Afterwards the used size is written to an output param. On success, true is returned.

Official sw retries using the cmd in a loop on error 0x8D4 with svcSleepThread(100000000) being used first.
 
Official sw uses permissions=None for the TransferMemory, with an user-specified buffer. The size of the buffer used by official sw is 0x6000000.
 
==== PrepareForJit ====
Takes no input. Launches the [[JIT_services|jit-sysmodule]] if it has not already been launched for the current application, storing a std::shared_ptr<> for jit-sysmodule process tracking object as an IApplicationFunctions member.
 
~IApplicationFunctions() includes:
 
    if (this->jit_process) {
        Terminate(this->jit_process);
        this->jit_process = nullptr;
    }
 
Thus the lifetime of the jit sysmodule is tied to the application which uses it, and each application gets its own fresh copy of the jit sysmodule.

Stubbed with an ILibraryAppletCreator from [[#CreateSelfLibraryAppletCreatorForDevelop]], just returns an error.
 
Gets whether any LibraryApplets ([[#ILibraryAppletAccessor]]) which were created by the current applet are still open (or by the Application when used from the [[#IApplicationAccessor]] cmd).
 
=== CreateStorage ===
Takes an input s64 for the storage size, returns an [[#IStorage]].
 
This allocates a buffer with the specified size which can then be accessed via [[#IStorageAccessor]].
 
=== CreateTransferMemoryStorage ===
Takes an input TransferMemory copy-handle, an input u8 bool, and an s64 size, returns an [[#IStorage]].
 
The user-process creates the TransferMemory with permissions=0.
 
The TransferMemory is mapped, which can then be accessed via [[#IStorageAccessor]]. The input bool controls whether writing to the storage is allowed: [[#Write]] will throw an error if this flag is not set.
 
=== CreateHandleStorage ===
Takes an input copy-handle and an input s64, returns an [[#IStorage]]. In some cases the s64 must not have the negative bit set.
 
The input can be arbitrary, however official sw is only (?) known to use this for TransferMemory (with s64=size).

Commands <=30 are inherited from [[#IAppletAccessor]]. GetLibraryAppletInfo is identical to the [[#ILibraryAppletSelfAccessor]] cmd.
The BOTW game uses this GamePlayRecording functionality from the main-nso "nninitStartup" function, with size 0x6000000(96MiB). The official GamePlayRecording-enable code does the following(this will panic on any failure):
* [[SVC|Creates]] TransferMemory using the input buffer and size, with permissions=0.
* Uses [[#InitializeGamePlayRecording]] with the TransferMemory.
* Closes the TransferMemory handle, + TransferMemory cleanup.
* Uses [[#SetGamePlayRecordingState]] with value 0x1.
This GamePlayRecording functionality presumably enables the video-recording usable starting with [[4.0.0]].

Officially notification messages are handled by the application itself, not sdk-nso in ExeFS. Official apps call code in sdk-nso which basically uses svcWaitSynchronization with the event from [[#GetEventHandle]] to check whether a message is available, then if so it uses [[#ReceiveMessage]]. The actual handling for message IDs is done in the app itself(see [[#AppletMessage]]).
This returns two u8s loaded from state, these are the same StorageIds from [[#ApplicationLaunchProperty]].


[7.0.0+] User-processes now use BeginVrModeEx/EndVrModeEx instead of [[#SetVrModeEnabled]]. Prior to using using BeginVrModeEx, [[Parental_Control_services|pctl]] IsStereoVisionPermitted is used and error 0xD08E is thrown if not allowed by pctl.

Used for sending requests to [[qlaunch]]. sdk-nso creates a 0x10-byte storage which is sent to this. The following are the functions which use this, with the data written to the storage:
Used to exit the application and return to the kiosk menu. Official sw uses [[#UnlockExit]] immediately before this if needed.
* <code>RequestHomeMenu</code> <code>5341 4d53 0100 0000 0200 0000 0100 0000</code> Returns to the main Home Menu, equivalent to pressing the HOME button.
* <code>RequestJumpToSystemUpdate</code> <code>5341 4d53 0100 0000 0b00 0000 0100 0000</code> Equivalent to entering "System Update" under System Settings. When leaving this, it returns to the main Home Menu.


=== GetHomeButtonReaderLockAccessor ===
On success, official sw will enter an infinite loop with sleep-thread value 86400000000000.
No input, returns an output [[#ILockAccessor]].


Similar to using [[#GetReaderLockAccessorEx]] with inval=0.
This throws an error when the cached [[Settings_services#GetQuestFlag]] value is 0.


=== GetReaderLockAccessorEx ===
==== EnableApplicationCrashReport ====
Takes an input u32, returns an output [[#ILockAccessor]].
Takes an input u8 bool, no output.


The input value must be 0-3. 0 = HomeButton.

Takes an input u32, returns an output [[#ILockAccessor]].


The input value must be 0-3. 0 = HomeButton.
User-processes create the tmem with an user-specified buffer with permissions=0. '''width''' = 1280 and '''height''' = 720.


=== GetCradleFwVersion ===
After the validation checks pass the input is passed to [[OMM_services|ommdisp]] cmd500.
No input, returns 4 output u32s.


This uses [[#omm]] GetCradleFwVersion.
This is used as an overlay for screenshots.


=== IsVrModeEnabled ===
==== SetApplicationCopyrightImage ====
No input, returns an output u8 bool.
Takes a type-0x45 input buffer, an s32 '''x''', an s32 '''y''', an s32 '''width''', an s32 '''height''', an s32 [[#WindowOriginMode]], and no output.


=== SetVrModeEnabled ===
'''x''' and '''y''' must not have the negative bit set. '''width''' and '''height''' must not be <1.
Takes an input u8 bool flag. No output.


Updates internal AM state fields. If the new state doesn't match the previous state, this uses the [[Backlight_services]] {Disable/Enable}VrMode command depending on whether flag={disable/enable}.
Sets the RGBA8 image for use with [[#InitializeApplicationCopyrightFrameBuffer]]. Overrides the current image, if this was already used previously.


When the VrMode is set to true, the console shows a screen rendered like vr asking the user to move his face away and hit the 'close' button. When this button is pressed, the console resets the vrMode to false.
==== SetApplicationCopyrightVisibility ====
 
=== SetLcdBacklighOffEnabled ===
Takes an input u8 bool, no output.

==== QueryApplicationPlayStatistics ====
No input/output.
Takes a type-0x6 output buffer containing an array of [[Shared_Database_services|ApplicationPlayStatistics]] and a type-0x5 input buffer containing an array of [[NCM_services#ApplicationId|ApplicationId]]. Returns an output s32 for actual total output entries.


Identical to [[#SetVrModeEnabled]] except with hard-coded flag=1.
The number of entries in each array is the same.


=== EndVrModeEx ===
See also [[NACP_Format#PlayLogQueryCapability|PlayLogQueryCapability]].
No input/output.


Identical to [[#SetVrModeEnabled]] except with hard-coded flag=0.
This uses [[Shared_Database_services|pdm:qry]] QueryApplicationPlayStatisticsForSystem.


=== IsInControllerFirmwareUpdateSection ===
==== QueryApplicationPlayStatisticsByUid ====
No input, returns an output u8 bool.
Takes a u128 userID, a type-0x6 output buffer containing an array of [[Shared_Database_services|ApplicationPlayStatistics]] and a type-0x5 input buffer containing an array of [[NCM_services#ApplicationId|ApplicationId]]. Returns an output s32 for actual total output entries.


=== GetDefaultDisplayResolution ===
Same as [[#QueryApplicationPlayStatistics]] except this uses [[Shared_Database_services|pdm:qry]] cmd16, to get playstats specific to userIDs.  
No input, returns two output s32s '''width''' and '''height'''.


=== GetDefaultDisplayResolutionChangeEvent ===
==== ExecuteProgram ====
No input, returns an output Event handle with autoclear=true.

==== UnpopToUserChannel ====
Takes an input s32 [[#TvPowerStateMatchingMode]], no output.
Takes an input [[#IStorage]], no output.


=== GetApplicationIdByContentActionName ===
The input storage is pushed to the UserChannel. This is the same channel used by [[#LaunchParameterKind]] value 1.
Takes a type-0x5 input buffer containing a string, returns an output [[NCM_services#ApplicationId|ApplicationId]].


Gets the ApplicationId for the specified ContentActionName string. Returns an error when the current [[#AppletId]] isn't 0x04 (when the current applet isn't a SystemApplication).
User-processes create a storage using data specified by the user (written to offset=0 size=inputsize), with max size 0x1000. This storage is then used with this cmd.


=== SetCpuBoostMode ===
==== GetPreviousProgramIndex ====
Takes an input u32 '''CpuBoostMode''' (only modes 0 and 1 are valid) and passes it to [[PPC_services#apm:sys|SetCpuBoostMode]].
No input, returns an output s32.


=== CancelCpuBoostMode ===
Gets the ProgramIndex of the Application which launched this title. The output ProgramIndex is -1 when there was no previous title.

=== PerformSystemButtonPressingIfInFocus ===
==== EnableApplicationAllThreadDumpOnCrash ====
Takes an input [[#SystemButtonType]], no output.
Takes an input u8 bool, no output.
 
==== GetGpuErrorDetectedSystemEvent ====
No input, returns an output Event handle with autoclear=false.
 
This is used by sdknso during applet-application initialization. A separate thread is setup where event-waiting is handled. When the Event is signaled, official sw will Abort.


Just returns 0 when a state field is not value 1. Verifies that the input button is allowed, then calls the same func as [[#PerformSystemButtonPressing]] internally.
==== SetDelayTimeToAbortOnGpuError ====
Takes an input s64 "nn::TimeSpan", no output.


=== SetPerformanceConfigurationChangedNotification ===
==== GetFriendInvitationStorageChannelEvent ====
Takes an input u8 bool, no output.
No input, returns an output Event handle with EventClearMode=0.


=== GetCurrentPerformanceConfiguration ===
This is exposed by sdknso under <code>nn::friends::</code>. This returns a ptr to the cached Event in global state, with the Event being loaded if not previously initialized.
No input, returns the result of calling [[PPC_services#apm:sys|GetCurrentPerformanceConfiguration]].


=== GetOperationModeSystemInfo ===
==== TryPopFromFriendInvitationStorageChannel ====
No input, returns an output u32.
No input, returns an output [[#IStorage]].


This returns the output from [[#GetOperationModeSystemInfo_2|omm GetOperationModeSystemInfo]].
This uses the same StorageChannel as [[#PushToFriendInvitationStorageChannel]].


=== GetSettingsPlatformRegion ===
This is exposed by sdknso under <code>nn::friends::</code>. When the storage_size is <0x10, this returns false. <code>data_size = storage_size-0x10;</code> Then the first 0x10-bytes from storage are read to stack, which is later copied to the output Uid on success prior to returning. Then the storage is read into the specified output buffer with storage-offset 0x10, where the size is <code>size = data_size > buf_size ? buf_size : data_size</code>. Reading is skipped if size is zero. Afterwards the used size is written to an output param. On success, true is returned.
No input, returns an output u8.


This just returns the output from [[Settings_services#GetPlatformRegion|setsys GetPlatformRegion]].
==== GetNotificationStorageChannelEvent ====
No input, returns an output Event handle with EventClearMode=0.


=== ActivateMigrationService ===
This is exposed by sdknso under <code>nn::notification::</code>. This returns a ptr to the cached Event in global state, with the Event being loaded if not previously initialized.
No input/output.


=== DeactivateMigrationService ===
==== TryPopFromNotificationStorageChannel ====
No input/output.
No input, returns an output [[#IStorage]].


== ISelfController ==
This uses the same StorageChannel as [[#PushToNotificationStorageChannel]].

Takes 8-bytes of input and a handle. Returns an [[#IMovieWriter]].
|-
 
| 40 || [[#CreateManagedDisplayLayer]]
This internally uses the GRC cmd to open an [[GRC_services|IMovieWriter]]. This is therefore not usable on NX since that cmd is stubbed.
|-
 
| 41 || [4.0.0+] [[#IsSystemBufferSharingEnabled]]
==== RequestExitApplicationAndTryPopMessage ====
|-
Takes an input [[#IStorage|IStorage]], no output.
| 42 || [4.0.0+] [[#GetSystemSharedLayerHandle]]
 
[21.0.0+] Now additionally takes a total of 0x18-bytes of input.
 
==== IsLanguageSelectionLimited ====
No input, returns 1-byte of output.
 
On NX this just writes 0 to output and returns 0.
 
==== StartContinuousRecordingFlushForDebug ====
Takes an input s64 nanoseconds-value, returns an output Event handle with autoclear=false.
 
The cached value loaded from [[System_Settings|system-setting]] <code>am.debug!dev_function</code> must be set to 0x1 with size 0x1, otherwise an error is returned.
 
==== CreateMovieMaker ====
Takes an input u64 size and a TransferMemory handle, returns an [[#IMovieMaker]].
 
Official sw retries using the cmd in a loop on error 0x8D4 with svcSleepThread(100000000) being used first.
 
Official sw uses permissions=None for the TransferMemory, with an user-specified buffer. The size of the buffer used by official sw is 0x6000000.
 
==== PrepareForJit ====
Takes no input. Launches the [[JIT_services|jit-sysmodule]] via [[NS_Services|ns]] LaunchLibraryApplet if it has not already been launched for the current application, storing a std::shared_ptr<> for jit-sysmodule process tracking object as an IApplicationFunctions member.
 
~IApplicationFunctions() includes:
 
    if (this->jit_process) {
        Terminate(this->jit_process);
        this->jit_process = nullptr;
    }
 
Thus the lifetime of the jit sysmodule is tied to the application which uses it, and each application gets its own fresh copy of the jit sysmodule.
 
AM can also optionally launch jit-sysmodule automatically if the [[NACP]] enables it.
 
[S2] This is no longer usable since this returns Result 0x408 (sysmodule doesn't exist).
 
=== IMovieWriter ===

=== Exit ===
=== CreateLibraryAppletOld ===
No input/output.
Unofficial name.


Exits the current applet. On success, official sw will enter an infinite loop with sleep-thread value 86400000000000.
Takes 2 input u32s [[#AppletId]] and [[#LibraryAppletMode]], returns an [[#ILibraryAppletAccessor]].


=== LockExit ===
=== TerminateAllLibraryApplets ===
No input/output.
No input/output.


Locks exit process of pressing X to close in HOME Menu for an application or HOME button for an applet. When locked, it will show the "waiting for software to be closed dialog" until UnlockExit is called or a 15 seconds timeout (when the latter occurs, the process is force-terminated).
Stubbed with an ILibraryAppletCreator from [[#CreateSelfLibraryAppletCreatorForDevelop]], just returns an error.


=== UnlockExit ===
Terminates all LibraryApplets which were created by the current applet (or by the Application when used from the [[#IApplicationAccessor]] cmd).
No input/output.


Unlocks exit process, if LockExit was previously used.
=== AreAnyLibraryAppletsLeft ===
No input, returns an output u8 bool.


=== EnterFatalSection ===
Stubbed with an ILibraryAppletCreator from [[#CreateSelfLibraryAppletCreatorForDevelop]], just returns an error.
No input/output.


=== LeaveFatalSection ===
Gets whether any LibraryApplets ([[#ILibraryAppletAccessor]]) which were created by the current applet are still open (or by the Application when used from the [[#IApplicationAccessor]] cmd).
No input/output.


[[#EnterFatalSection]] must be executed at least once before executing this command, otherwise error code 0x40080 will be returned. EnterFatalSection and LeaveFatalSection work in pairs, that is, N calls to EnterFatalSection must be performed first in order to perform N executions of LeaveFatalSection. Essentially, these two functions operate like how one would lock and unlock a recursive mutex.
=== CreateLibraryApplet ===
Unofficial name.


=== GetLibraryAppletLaunchableEvent ===
Takes 2 input u32s [[#AppletId]] and [[#LibraryAppletMode]], an u64 ThreadId, returns an [[#ILibraryAppletAccessor]].
No input, returns an output event handle with autoclear=false.


=== SetScreenShotPermission ===
The ThreadId is from the current-thread of the user-process which is using the cmd.
Takes an input s32. No output.


Controls whether screenshot-capture is allowed.
=== CreateStorage ===
Takes an input s64 for the storage size, returns an [[#IStorage]].


{| class="wikitable" border="1"
This allocates a buffer with the specified size which can then be accessed via [[#IStorageAccessor]].

=== SetPerformanceModeChangedNotification ===
The user-process creates the TransferMemory with permissions=0.
Takes an input u8 bool flag. No output.


=== SetFocusHandlingMode ===
The TransferMemory is mapped, which can then be accessed via [[#IStorageAccessor]]. The input bool controls whether writing to the storage is allowed: [[#Write]] will throw an error if this flag is not set.
Takes 3 input u8s with each field located immediately after the previous u8, these are bool flags. No output.


=== SetRestartMessageEnabled ===
=== CreateHandleStorage ===
Takes an input u8 bool flag, no output.
Takes an input copy-handle and an input s64, returns an [[#IStorage]]. In some cases the s64 must not have the negative bit set.


See [[#AppletMessage]].
The input can be arbitrary, however official sw is only (?) known to use this for TransferMemory (with s64=size).

Commands <=30 are inherited from [[#IAppletAccessor]]. GetLibraryAppletInfo is identical to the [[#ILibraryAppletSelfAccessor]] cmd.


The input u32 is "nn::settings::KeyboardLayout".
==== SetOutOfFocusApplicationSuspendingEnabled ====
Takes an input u8 bool, no output.


=== CreateManagedDisplayLayer ===
Official sw will assert prior to using this if applet-service was not initialized as *Application.
Returns an output u64 LayerId which is then used by the user-process with [[Display_services#OpenLayer]].


=== IsSystemBufferSharingEnabled ===
==== PresetLibraryAppletGpuTimeSliceZero ====
No input/output.
No input/output.


Not available when the current applet is an Application ([[#AppletId]] == 0x01).
sdknso only uses with with [[Software_Keyboard|swkbd-inline]], immediately after creating the LibraryApplet.


Checks whether SystemBufferSharing is enabled, throwing an error otherwise.
==== PushInData ====
Takes an input [[#IStorage]], no output.


=== GetSystemSharedLayerHandle ===
==== PopOutData ====
No input, returns two output u64s "nn::vi::fbshare::SharedBufferHandle" and "nn::vi::fbshare::SharedLayerHandle".
No input, returns an output [[#IStorage]].


Runs code similar to [[#IsSystemBufferSharingEnabled]] first.
==== PushExtraStorage ====
Takes an input [[#IStorage]], no output.


=== GetSystemSharedBufferHandle ===
==== PushInteractiveInData ====
No input, returns an output u64 "nn::vi::fbshare::SharedBufferHandle".
Takes an input [[#IStorage]], no output.


Runs code similar to [[#IsSystemBufferSharingEnabled]] first.
==== PopInteractiveOutData ====
No input, returns an output [[#IStorage]].


Same as [[#GetSystemSharedLayerHandle]] except this just gets the SharedBufferHandle.
==== GetPopOutDataEvent ====
No input, returns an output handle with autoclear=false.


=== CreateManagedDisplaySeparableLayer ===
==== GetPopInteractiveOutDataEvent ====
No input, returns two output u64 LayerIds.
No input, returns an output event handle with autoclear=false.


sdknso now uses this instead of [[#CreateManagedDisplayLayer]]. sdknso caches the output from the cmd so that it's only used once. The first u64 is used the same as the original LayerId from [[#CreateManagedDisplayLayer]]. <code>nn::vi::CreateRecordingLayer</code> uses the second LayerId, the layer creation is identical besides which LayerId is used.
==== NeedsToExitProcess ====
No input, returns an output u8 bool.


=== SetManagedDisplayLayerSeparationMode ===
Stubbed, just returns an error.
Takes an input u32, no output.


sdknso exposes this as <code>nn::vi::SetRecordingLayerEnabled(bool)</code>.
==== RequestForAppletToGetForeground ====
No input/output.


The input u32 must be 0-1.
Stubbed, just returns an error.


=== SetHandlesRequestToDisplay ===
==== GetIndirectLayerConsumerHandle ====
Takes an input u8 bool, no output.
Takes an input PID and an input u64 AppletResourceUserId, returns an output u64 IndirectLayerConsumerHandle.


Sets an internal state flag. When the input flag is 0, this will in additional run the same code as [[#ApproveToDisplay]].
Official sw uses this during LibraryApplet creation when [[#LibraryAppletMode]] is 0x3.


See [[#AppletMessage]].
== ICommonStateGetter ==
This is "nn::am::service::ICommonStateGetter".


=== ApproveToDisplay ===
{| class="wikitable" border="1"

=== IsIlluminanceAvailable ===
Officially notification messages are handled by the application itself, not sdk-nso in ExeFS. Official apps call code in sdk-nso which basically uses svcWaitSynchronization with the event from [[#GetEventHandle]] to check whether a message is available, then if so it uses [[#ReceiveMessage]]. The actual handling for message IDs is done in the app itself(see [[#AppletMessage]]).
No input, returns an output u8 bool.


Uses [[Backlight_services|lbl]] command IsAmbientLightSensorAvailable.
[7.0.0+] User-processes now use BeginVrModeEx/EndVrModeEx instead of [[#SetVrModeEnabled]]. Prior to using using BeginVrModeEx, [[Parental_Control_services|pctl]] IsStereoVisionPermitted is used and error 0xD08E is thrown if not allowed by pctl.


User-processes can use this to determine whether to continue with using GetCurrentIlluminance(Ex).
=== GetEventHandle ===
No input. Returns an output event handle. This is signalled when a message is available with [[#ReceiveMessage]].


=== SetAutoSleepDisabled ===
=== ReceiveMessage ===
Takes an input u8 bool, no output.
No input. Returns an output [[#AppletMessage]]. Error 0x680 indicates no message is available.


=== IsAutoSleepDisabled ===
=== GetThisAppletKind ===
No input, returns an output u8 bool.
No input, returns an output [[#AppletKind]].


=== ReportMultimediaError ===
Stubbed, just returns an error.
Takes an input Result and a type-0x5 input buffer, no output.


The buffer contains a 0x138-byte "movie::MultimediaTelemetryReport" struct.
=== AllowToEnterSleep ===
No input/output.


=== GetCurrentIlluminanceEx ===
Stubbed, just returns an error.
No input, returns an output u8 bool and float.


Uses [[Backlight_services|lbl]] command GetAmbientLightSensorValue.
=== DisallowToEnterSleep ===
No input/output.


=== SetInputDetectionPolicy ===
Stubbed, just returns an error.
Takes an input [[#InputDetectionPolicy]], no output.


=== SetWirelessPriorityMode ===
=== GetOperationMode ===
Takes an input s32 enum '''WirelessPriorityMode''', no output.
No input. Returns an output u8 for the current [[#OperationMode]].


The input value must be 1 or 2.
=== GetPerformanceMode ===
No input. Returns an output u32 for the current [[#PerformanceMode]].


=== GetAccumulatedSuspendedTickValue ===
=== GetCradleStatus ===
No input, returns an output u64 tick value.
No input, returns an output u8.


Gets the total time in ticks that the process was suspended, relative to when the applet-service was last initialized.
This uses [[#omm]] GetCradleStatus.


=== GetAccumulatedSuspendedTickChangedEvent ===
=== GetBootMode ===
No input, returns an output Event handle with autoclear=true.
No input, returns an output u8.
 
Returns the value from [[Process_Manager_services|pm:bm]] GetBootMode.


This is signaled when the output from [[#GetAccumulatedSuspendedTickValue]] is updated.
=== GetCurrentFocusState ===
No input. Returns an output u8 [[#FocusState]].


=== SetAlbumImageTakenNotificationEnabled ===
=== RequestToAcquireSleepLock ===
Takes an input u8 bool, no output.
No input/output.


See [[#AppletMessage]].
=== ReleaseSleepLock ===
No input/output.


=== SetApplicationAlbumUserData ===
=== ReleaseSleepLockTransiently ===
Takes a type-0x21 input buffer, no output.
No input/output.


The buffer contains arbitrary UserData.
=== GetAcquiredSleepLockEvent ===
No input, returns an output Event handle with autoclear=false.


The size must be <=0x400. The input buffer is copied to a buffer loaded from a state ptr (throwing an error when the state ptr is not set), with the u32 size being written to statebuf+0x400 afterwards.
=== GetWakeupCount ===
No input, returns an output u64.


=== GetDebugStorageChannel ===
=== PushToGeneralChannel ===
No input, returns an output [[#IStorageChannel]].
Takes an input [[#IStorage]], no output.


The cached value loaded from [[System_Settings|system-setting]] <code>am.debug!dev_function</code> must be set to 0x1 with size 0x1, otherwise an error is returned.
This is not usable under an Application, however it is usable under a LibraryApplet.


== IStorageChannel ==
Used for sending requests to [[qlaunch]]. sdk-nso creates a 0x10-byte storage which is sent to this. The following are the functions which use this, with the data written to the storage:
Added with [[7.0.0]].
* <code>RequestHomeMenu</code> <code>5341 4d53 0100 0000 0200 0000 0100 0000</code> Returns to the main Home Menu, equivalent to pressing the HOME button.
* <code>RequestJumpToSystemUpdate</code> <code>5341 4d53 0100 0000 0b00 0000 0100 0000</code> Equivalent to entering "System Update" under System Settings. When leaving this, it returns to the main Home Menu.

=== GetAccumulatedSuspendedTickValue ===
This section documents library applet launching.
No input, returns an output u64 tick value.


Before starting the applet, [[#IStorage]]s are [[#ILibraryAppletCreator|created]] and written, then passed to [[#ILibraryAppletAccessor]] PushInData. The [[#IStorage]] session is closed afterwards. The first [[#IStorage]] is [[#CommonArguments]], followed by any applet-specific [[#IStorage]]s.
Gets the total time in ticks that the process was suspended, relative to when the applet-service was last initialized.


Once the applet finishes running successfully, [[#ILibraryAppletAccessor]] PopOutData can be used to get the applet-specific [[#IStorage]] containing the applet output data.
=== GetAccumulatedSuspendedTickChangedEvent ===
No input, returns an output Event handle with autoclear=true.


== CommonArguments ==
This is signaled when the output from [[#GetAccumulatedSuspendedTickValue]] is updated.
The first [[#CreateStorage|IStorage]] passed to applets should contain the common library applet arguments. This is populated by <code>nn::la::CommonArgumentsWriter</code> and has the following format.


This struct is 0x20-bytes.
=== SetAlbumImageTakenNotificationEnabled ===
Takes an input u8 bool, no output.


Official sw handles the first 8-bytes separately, which is a header. With CommonArguments version 0x0, the header is 4-bytes, while starting with version 0x1 it's 8-bytes.

Takes a total of 0x10-bytes of input and a PID, no output.
 
This is a wrapper for [[Capture_services|caps:c]] cmd33. Commands '''SaveScreenShot''', '''SaveScreenShotEx0''', '''SaveScreenShotEx1''' and '''SaveScreenShotEx2''' are wrappers for [[Display_services|caps:sc]] cmd210.
 
== SaveScreenShot ==
Takes two input u32s, an u64 AppletResourceUserId, a PID, and a type-0x45 input buffer containing image data. Returns an [[Capture_services|ApplicationAlbumEntry]].
 
Official user-processes doesn't use this, instead [[#SaveScreenShotEx0]] is used: ScreenShotAttributeEx0 is all-zero, except +4 is set to an input u32 and u32 +0xC = 0x1.
 
This cmd internally uses an all-zero ScreenShotAttributeEx0, with u32 +0 = input u32 and u32 +0x8 = 0x3.
 
== SaveScreenShotEx0 ==
Takes an input 0x40-byte struct '''ScreenShotAttributeEx0''', an input u32, an input u64 AppletResourceUserId, a PID, and a type-0x45 input buffer containing image data. Returns an [[Capture_services|ApplicationAlbumEntry]].
 
== SaveScreenShotEx1 ==

= Library Applets =
This section documents library applet launching.
 
Before starting the applet, [[#IStorage]]s are [[#ILibraryAppletCreator|created]] and written, then passed to [[#ILibraryAppletAccessor]] PushInData. The [[#IStorage]] session is closed afterwards. The first [[#IStorage]] is [[#CommonArguments]], followed by any applet-specific [[#IStorage]]s.
 
Once the applet finishes running successfully, [[#ILibraryAppletAccessor]] PopOutData can be used to get the applet-specific [[#IStorage]] containing the applet output data.
 
== CommonArguments ==
The first [[#CreateStorage|IStorage]] passed to applets should contain the common library applet arguments. This is populated by <code>nn::la::CommonArgumentsWriter</code> and has the following format.
 
This struct is 0x20-bytes.
 
Official sw handles the first 8-bytes separately, which is a header. With CommonArguments version 0x0, the header is 4-bytes, while starting with version 0x1 it's 8-bytes.

This struct is "nn::am::service::AppletResourceUsageInfo". This struct is 0x20-bytes.
An object constructor also writes the output from [[Process_Manager_services|pm:bm]] GetBootMode into the created object. A vfunc for this object checks whether this field is Maintenance: if so, it calls a vfunc then a func and returns. Otherwise after calling various (v)funcs, if required this eventually uses [[OMM_services|ommdisp]] cmd600.
