View source for Applet Manager services

AM (Applet Manager) provides services for interacting with system applets while abstracting several aspects of power and operation management.

Contains multiple raw images, with at least the following: "NN_OMM_CHARGING_BIN_{begin|end}"(charging icon), low-battery icon, and the Nintendo Switch logo displayed during system boot.

All of these Open*Proxy commands except [[#OpenLibraryAppletProxy]] take the same input as [[#OpenApplicationProxy]], with the same user-process retry-loop as [[#OpenApplicationProxy]]. These Open*Proxy commands (including appletOE) doesn't seem to usable from processes which aren't actual applets (such as sysmodules), at least for applet-types which aren't already in use.

OpenLibraryAppletProxyOld eventually calls the same func as [[#OpenLibraryAppletProxy]], except that the [[#AppletAttribute]] is all-zero.

This service is used by all system non-regular-applications.

The 01000000000010XX system [[Title_list|titles]] use the following applet types(above Open{type}Proxy commands):
* "qlaunch": SystemApplet
* "overlay": OverlayApplet
* "starter": SystemApplication
* "maintenance": SystemApplet
* All others: LibraryApplet

== OpenLibraryAppletProxy ==
Returns an [[#ILibraryAppletProxy]].

Takes a [[IPC_Marshalling|reserved]] input u64(official user-processes use hard-coded value 0), a PID,a process copy-handle(cur-proc handle alias), and a type-0x15 input buffer containing an [[#AppletAttribute]].

Official user-processes use the same retry loop with this as the other Open*Proxy commands.

== CreateSelfLibraryAppletCreatorForDevelop ==
Takes a PID and an input u64 pid_placeholder, returns an [[#ILibraryAppletCreator]].

The cached value loaded from [[Settings_services#GetDebugModeFlag]] must be 1, otherwise an error is returned.

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.

== GetSystemAppletControllerForDebug ==
No input, returns an [[#ISystemAppletControllerForDebug]].

The cached value loaded from [[System_Settings|system-setting]] <code>am.debug!dev_function</code> must be set to 0x1 with size 0x1, and various state checks must pass, otherwise 0 is returned with no output interface.

== GetDebugFunctions ==
No input, returns an [[#IDebugFunctions]].

The cached value loaded from [[System_Settings|system-setting]] <code>am.debug!dev_function</code> must be set to 0x1 with size 0x1, otherwise 0 is returned with no output interface.

Commands <=30 are inherited from [[#IAppletAccessor]].

===== RequestForApplicationToGetForeground =====
No input/output.

===== GetCurrentLibraryApplet =====
No input, returns an output [[#IAppletAccessor]].

===== GetApplicationId =====
No input, returns an output [[NCM_services#ApplicationId|ApplicationId]].

===== PushLaunchParameter =====
Takes an input u32 [[#LaunchParameterKind]] and an input [[#IStorage]], no output.

===== GetApplicationControlProperty =====
No input, takes a type-0x6 output buffer.

The output buffer must be at least 0x4000-bytes. Returns an error when the [[#AppletId]] is 0x04, aka when the IApplicationAccessor is for a SystemApplication. 

This gets the application [[NACP_Format|control.nacp]].

===== GetApplicationLaunchProperty =====
Takes a type-0x6 output buffer.

The output buffer size must be at least 0x10-bytes. Returns an error when the [[#AppletId]] is 0x04, aka when the IApplicationAccessor is for a SystemApplication.

This gets the [[#ApplicationLaunchProperty]].

===== GetApplicationLaunchRequestInfo =====
No input, returns an output 0x10-byte struct.

This gets the [[#ApplicationLaunchRequestInfo]] from state. The output struct is "nn::applet::ApplicationLaunchRequestInfo".

===== SetUsers =====
Takes an input u8 bool flag and a type-0x5 input buffer containing an array of u128 userIDs.

The total entries for the userIDs must be <=8.

When the input flag is true, this just clears the '''users_available''' state flag to 0 and returns.

===== CheckRightsEnvironmentAvailable =====
No input, returns an output u8 bool.

===== GetNsRightsEnvironmentHandle =====
No input, returns an output u64.

===== GetDesirableUids =====
Takes a type-0x6 output buffer containing an array of u128 userIDs, returns an output s32 '''total_entries'''.

Gets a userID listing, this is unrelated to [[#SetUsers]]. [[qlaunch]] only uses 1 userID with this.

The stored entry-count in state must be <= <size of output buffer in entries>.

===== ReportApplicationExitTimeout =====
No input/output.

===== SetApplicationAttribute =====
Takes a type-0x15 input buffer containing an [[#ApplicationAttribute]], no output.

===== HasSaveDataAccessPermission =====
Takes an input [[NCM_services#ApplicationId|ApplicationId]], returns an output u8 bool flag.

Gets whether the savedata specified by the input ApplicationId is accessible. The output flag indicates whether it's accessible.

If the ApplicationId matches the current application, this immediately returns success with flag=1.

===== PushToFriendInvitationStorageChannel =====
Takes an input [[#IStorage]], no output.

Clears the FriendInvitation StorageChannel, then pushes the input storage there.

===== PushToNotificationStorageChannel =====
Takes an input [[#IStorage]], no output.

Clears the Notification StorageChannel, then pushes the input storage there.

[[qlaunch]] will only push data for this when launching the Application when the Alarm was triggered, where the system was previously in sleep-mode. This data is the [[Glue_services|Notification]] ApplicationParameter.

===== RequestApplicationSoftReset =====
No input/output.

===== RestartApplicationTimer =====
No input/output.

===== IAppletAccessor =====

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.

=== IsVrModeCurtainRequired ===
No input, returns an output bool.

=== SetCpuBoostRequestPriority ===
Takes an input s32, no output.

Takes an input u64 size and a TransferMemory handle, returns a GRC [[GRC_services#IGameMovieTrimmer|IGameMovieTrimmer]].

This is a wrapper for GRC [[GRC_services#OpenGameMovieTrimmer|OpenGameMovieTrimmer]].

Official sw uses an user-buffer for the tmem, with permissions=0.

==== ReserveResourceForMovieOperation ====
No input/output.

Updates state fields. This must be used before [[#CreateGameMovieTrimmer]].

==== UnreserveResourceForMovieOperation ====
No input/output.

Updates state fields. This must be used once finished with [[GRC_services#IGameMovieTrimmer|IGameMovieTrimmer]].

==== GetMainAppletAvailableUsers ====
Takes a type-0x6 output buffer containing an array of u128 userIDs, returns an output u8 bool and a s32 '''total_entries'''.

This gets the userIDs previously set by [[#SetUsers]].

The size of the output buffer in entries must be at least 8.

Normally the output bool is set to 0, however when no users are available it's set to 1 with '''total_entries''' = -1.

==== SetApplicationMemoryReservation ====
Takes an input u64, no output.

An Application must be currently running. The input u64 must be 0x1000-byte aligned.

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]].

==== PopLaunchParameter ====
Takes an input u32 [[#LaunchParameterKind]], returns an output [[#IStorage]].

Pops a LaunchParameter [[#IStorage]], the storage will be removed from sysmodule state during this.

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

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

==== CreateApplicationAndRequestToStartForQuest ====
Takes 2 input u32s (loaded from struct [[#ApplicationAttributeForQuest]]) and an input [[NCM_services#ApplicationId|ApplicationId]], no output.

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

==== CreateApplicationWithAttributeAndPushAndRequestToStartForQuest ====
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]].

==== CreateApplicationWithAttributeAndRequestToStartForQuest ====
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]].

==== EnsureSaveData ====
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.

Creates the various savedata as specified by the application [[NACP_Format|control.nacp]] when the savedata doesn't exist.

Official user-processes launch the dataErase LibraryApplet depending on the Result, the above output size is used with this.

==== GetDesiredLanguage ====
No input, returns an output [[Settings_services#LanguageCode|LanguageCode]].

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

For example, in some cases official apps use this with [[Error_codes|error]] 0x2A2 then uses svcBreak.

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

The output struct is "nn::oe::DisplayVersion". This the DisplayVersion string copied from the application [[NACP_Format|control.nacp]], this is always NUL-terminated.

==== GetLaunchStorageInfoForDebug ====
No input, returns an output u8 [[Filesystem_services#StorageId|StorageId]] and u8 [[Filesystem_services#StorageId|StorageId]].

This returns two u8s loaded from state, these are the same StorageIds from [[#ApplicationLaunchProperty]].

No input, returns two output s64s.

==== NotifyRunning ====
Takes no input. Returns an output u8 bool, which is ignored by official user-processes.

==== GetPseudoDeviceId ====
No input, returns an output 0x10-byte "nn::util::Uuid" struct.

The 0x20-byte output data from [[NS_Services|GetSystemSeedForPseudoDeviceId]] followed by the 8-byte [[NACP_Format|SeedForPseudoDeviceId]] from the current control.nacp, is hashed with SHA1. Then "nn::util::GenerateUuidVersion5" is called with the final hash, the output from this is then returned for the Uuid.

==== SetMediaPlaybackStateForApplication ====
Takes an input u8 bool, no output.

==== IsGamePlayRecordingSupported ====
No input, returns an output u8 bool.

==== InitializeGamePlayRecording ====
Takes a TransferMemory handle and an u64 for the size of the TransferMemory. The size must match 0x6000000 otherwise an error is returned.

==== SetGamePlayRecordingState ====
Takes an input u32. 0 = disable/pause, 1 = enable/restart.

==== RequestFlushGamePlayingMovieForDebug ====
No input/output.

Requests to save the video recording, as if the Capture-button was held.

==== RequestToShutdown ====
No input/output.

On success, official sw will enter an infinite loop with sleep-thread value 86400000000000.

==== RequestToReboot ====
No input/output.

On success, official sw will enter an infinite loop with sleep-thread value 86400000000000.

==== RequestToSleep ====
No input/output.

==== ExitAndRequestToShowThanksMessage ====
No input/output.

Used to exit the application and return to the kiosk menu. Official sw uses [[#UnlockExit]] immediately before this if needed.

On success, official sw will enter an infinite loop with sleep-thread value 86400000000000.

This throws an error when the cached [[Settings_services#GetQuestFlag]] value is 0.

==== EnableApplicationCrashReport ====
Takes an input u8 bool, no output.

==== InitializeApplicationCopyrightFrameBuffer ====
Takes an input TransferMemory handle, an s32 '''width''', an s32 '''height''', an u64 tmem_size, and no output.

tmem_size must be 0x40000-byte aligned. '''width''' must be 1-1280, and '''height''' must be 1-720.

User-processes create the tmem with an user-specified buffer with permissions=0. '''width''' = 1280 and '''height''' = 720.

This is used as an overlay for screenshots.

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

'''x''' and '''y''' must not have the negative bit set. '''width''' and '''height''' must not be <1.

Sets the RGBA8 image for use with [[#InitializeApplicationCopyrightFrameBuffer]]. Overrides the current image, if this was already used previously.

==== SetApplicationCopyrightVisibility ====
Takes an input u8 bool, no output.

Sets the visibility for the image set by [[#SetApplicationCopyrightImage]], in screenshots. By default it's visible.

==== QueryApplicationPlayStatistics ====
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.

The number of entries in each array is the same.

See also [[NACP_Format#PlayLogQueryCapability|PlayLogQueryCapability]].

This uses [[Shared_Database_services|pdm:qry]] QueryApplicationPlayStatisticsForSystem.

==== QueryApplicationPlayStatisticsByUid ====
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.

Same as [[#QueryApplicationPlayStatistics]] except this uses [[Shared_Database_services|pdm:qry]] cmd16, to get playstats specific to userIDs. 

==== ExecuteProgram ====
Takes an input u32 [[#ProgramSpecifyKind]] and an input u64, no output.

==== ClearUserChannel ====
No input/output.

Clears the UserChannel used by [[#UnpopToUserChannel]].

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

The input storage is pushed to the UserChannel. This is the same channel used by [[#LaunchParameterKind]] value 1.

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.

==== GetPreviousProgramIndex ====
No input, returns an output s32.

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

==== EnableApplicationAllThreadDumpOnCrash ====
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.

==== SetDelayTimeToAbortOnGpuError ====
Takes an input s64 "nn::TimeSpan", no output.

==== GetFriendInvitationStorageChannelEvent ====
No input, returns an output Event handle with EventClearMode=0.

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.

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

This uses the same StorageChannel as [[#PushToFriendInvitationStorageChannel]].

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.

==== GetNotificationStorageChannelEvent ====
No input, returns an output Event handle with EventClearMode=0.

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.

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

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

This is exposed by sdknso under <code>nn::notification::</code>. The storage is read into the specified output buffer, where the size is <code>size = storage_size > buf_size ? buf_size : storage_size</code>. Reading is skipped if size is zero. Afterwards the used size is written to an output param.

==== GetHealthWarningDisappearedSystemEvent ====
No input, returns an output Event with EventClearMode=0.

==== SetHdcpAuthenticationActivated ====
Takes an input u8 bool, no output.

==== GetLaunchRequiredVersion ====
Takes an input [[NCM_services#ApplicationId|ApplicationId]], an u64, returns an output [[#LaunchRequiredVersion]].

sdknso passes hard-coded value 0 for the u64.

==== UpgradeLaunchRequiredVersion ====
Takes an input [[#LaunchRequiredVersion]], an [[NCM_services#ApplicationId|ApplicationId]], an u64, no output.

sdknso passes hard-coded value 0 for the u64.

==== SendServerMaintenanceOverlayNotification ====
Takes two input [[PCV_services#PosixTime|PosixTime]], no output.

The second input value can optionally be 0.

==== GetLastApplicationExitReason ====
No input, returns an output s32.

==== 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]] 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.

=== CreateLibraryApplet ===
Takes 2 input u32s [[#AppletId]] and [[#LibraryAppletMode]], returns an [[#ILibraryAppletAccessor]].

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

Stubbed with an ILibraryAppletCreator from [[#CreateSelfLibraryAppletCreatorForDevelop]], just returns an error.

Terminates all LibraryApplets which were created by the current applet (or by the Application when used from the [[#IApplicationAccessor]] cmd).

=== AreAnyLibraryAppletsLeft ===
No input, returns an output u8 bool.

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).

==== SetOutOfFocusApplicationSuspendingEnabled ====
Takes an input u8 bool, no output.

Official sw will assert prior to using this if applet-service was not initialized as *Application.

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

sdknso only uses with with [[Software_Keyboard|swkbd-inline]], immediately after creating the LibraryApplet.

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]]).

[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.

=== GetEventHandle ===
No input. Returns an output event handle. This is signalled when a message is available with [[#ReceiveMessage]].

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

=== PushToGeneralChannel ===
Takes an input [[#IStorage]], no output.

This is not usable under an Application, however it is usable under a LibraryApplet.

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:
* <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 ===
No input, returns an output [[#ILockAccessor]].

Similar to using [[#GetReaderLockAccessorEx]] with inval=0.

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

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

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

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

This uses [[#omm]] GetCradleFwVersion.

=== IsVrModeEnabled ===
No input, returns an output u8 bool.

=== SetVrModeEnabled ===
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}.

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.

=== SetLcdBacklighOffEnabled ===
Takes an input u8 bool, no output.

Sets whether the LCD screen blacklight is turned off.

=== BeginVrModeEx ===
No input/output.

Identical to [[#SetVrModeEnabled]] except with hard-coded flag=1.

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).

=== SetCpuBoostMode ===
Takes an input u32 [[#CpuBoostMode]] and passes it to [[PPC_services#apm:sys|SetCpuBoostMode]].

=== CancelCpuBoostMode ===
No input/output.

=== GetBuiltInDisplayType ===
No input, returns an output s32.

This is not exposed by sdknso.

This loads a s32 index from global state (originates from [[SPL_services#GetConfig|GetConfig]] [[SMC#HardwareType|HardwareType]]), Aborts if it's out-of-bounds, then the following is returned for the output s32: global_array[loaded_index].

=== PerformSystemButtonPressingIfInFocus ===

=== LockExit ===
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).

=== UnlockExit ===
No input/output.

Unlocks exit process, if LockExit was previously used.

=== EnterFatalSection ===
No input/output.

=== LeaveFatalSection ===
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.

=== GetLibraryAppletLaunchableEvent ===
No input, returns an output event handle with autoclear=false.

=== SetScreenShotPermission ===
Takes an input s32. No output.

Controls whether screenshot-capture is allowed.

'''SetShimLibraryVersion''' 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 ==
Takes an input 0x40-byte struct '''ScreenShotAttributeEx0''', an input u32, an input u64 AppletResourceUserId, a PID, a type-0x15 input buffer containing an [[Capture_services|ApplicationData]], and a type-0x45 input buffer containing image data. Returns an [[Capture_services|ApplicationAlbumEntry]].

== SaveScreenShotEx2 ==
Takes an input 0x40-byte struct '''ScreenShotAttributeEx0''', an input u32, an input u64 AppletResourceUserId, a type-0x15 input buffer containing an [[Capture_services|UserIdList]], and a type-0x45 input buffer containing image data. Returns an [[Capture_services|ApplicationAlbumEntry]].

= 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.
