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.

==== PrepareForJit ====
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.
Takes no input. Launches title 010000000000003B (currently not present on retail systems) if some context variable is not set, with that context variable being initialized afterwards.

This internally uses the GRC cmd to open an [[GRC_services|IMovieWriter]]. This is therefore not usable on NX since that cmd is stubbed.
 
==== StartContinuousRecordingFlushForDebug ====
Takes an input s64 nanoseconds-value, returns an output Event handle with autoclear=false.


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


=== AreAnyLibraryAppletsLeft ===
==== CreateMovieMaker ====
No input, returns an output u8 bool.
Takes an input u64 size and a TransferMemory handle, returns an [[#IMovieMaker]].


Stubbed with an ILibraryAppletCreator from [[#CreateSelfLibraryAppletCreatorForDevelop]], just returns an error.
Official sw retries using the cmd in a loop on error 0x8D4 with svcSleepThread(100000000) being used first.


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).
Official sw uses permissions=None for the TransferMemory, with an user-specified buffer. The size of the buffer used by official sw is 0x6000000.


=== CreateStorage ===
==== PrepareForJit ====
Takes an input s64 for the storage size, returns an [[#IStorage]].
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.


This allocates a buffer with the specified size which can then be accessed via [[#IStorageAccessor]].
~IApplicationFunctions() includes:


=== CreateTransferMemoryStorage ===
    if (this->jit_process) {
Takes an input TransferMemory copy-handle, an input u8 bool, and an s64 size, returns an [[#IStorage]].
        Terminate(this->jit_process);
        this->jit_process = nullptr;
    }


The user-process creates the TransferMemory with permissions=0.
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.


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.
AM can also optionally launch jit-sysmodule automatically if the [[NACP]] enables it.


=== CreateHandleStorage ===
=== IMovieWriter ===
Takes an input copy-handle and an input s64, returns an [[#IStorage]]. In some cases the s64 must not have the negative bit set.
This is "nn::am::service::IMovieWriter".


The input can be arbitrary, however official sw is only (?) known to use this for TransferMemory (with s64=size).
This was added with [19.0.0+].

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


==== PopOutData ====
=== AreAnyLibraryAppletsLeft ===
No input, returns an output [[#IStorage]].
No input, returns an output u8 bool.


==== PushExtraStorage ====
Stubbed with an ILibraryAppletCreator from [[#CreateSelfLibraryAppletCreatorForDevelop]], just returns an error.
Takes an input [[#IStorage]], no output.


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


==== PopInteractiveOutData ====
=== CreateStorage ===
No input, returns an output [[#IStorage]].
Takes an input s64 for the storage size, returns an [[#IStorage]].


==== GetPopOutDataEvent ====
This allocates a buffer with the specified size which can then be accessed via [[#IStorageAccessor]].
No input, returns an output handle with autoclear=false.


==== GetPopInteractiveOutDataEvent ====
=== CreateTransferMemoryStorage ===
No input, returns an output event handle with autoclear=false.
Takes an input TransferMemory copy-handle, an input u8 bool, and an s64 size, returns an [[#IStorage]].


==== NeedsToExitProcess ====
The user-process creates the TransferMemory with permissions=0.
No input, returns an output u8 bool.


Stubbed, just returns an error.
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.


==== RequestForAppletToGetForeground ====
=== CreateHandleStorage ===
No input/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.


Stubbed, just returns an error.
The input can be arbitrary, however official sw is only (?) known to use this for TransferMemory (with s64=size).


==== GetIndirectLayerConsumerHandle ====
=== ILibraryAppletAccessor ===
Takes an input PID and an input u64 AppletResourceUserId, returns an output u64 IndirectLayerConsumerHandle.
This is "nn::am::service::ILibraryAppletAccessor".


Official sw uses this during LibraryApplet creation when [[#LibraryAppletMode]] is 0x3.

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


[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.

The actual handling for message IDs is done in the app itself(see [[#AppletMessage]]).
No input, returns an output u8 bool.


=== SetVrModeEnabled ===
[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.
Takes an input u8 bool flag. No output.

Depending on whether a state field is 0, this just returns an error or returns 0.
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.


=== AcquireLastForegroundCaptureSharedBuffer ===
=== SaveCurrentScreenshot ===
No input, returns an output u8 bool and an s32.
Takes an input s32 [[Capture_services#AlbumReportOption|AlbumReportOption]], no output.

'''SetShimLibraryVersion''' is a wrapper for [[Capture_services|caps:c]] cmd33. Commands '''SaveScreenShot''', '''SaveScreenShotEx0''', '''SaveScreenShotEx1''' and '''SaveScreenShotEx2''' are wrappers for [[Display_services|caps:sc]] cmd210.
=== AcquireLastApplicationCaptureBuffer ===
No input, returns an output handle.


== SaveScreenShot ==
Stubbed, just returns an error.
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.
=== ReleaseLastApplicationCaptureBuffer ===
No input/output.


This cmd internally uses an all-zero ScreenShotAttributeEx0, with u32 +0 = input u32 and u32 +0x8 = 0x3.
Clears a state field if it's not already 0, returning an error otherwise. On newer sysvers: then a func is called which just returns 0, then this cmd returns 0.


== SaveScreenShotEx0 ==
=== AcquireLastForegroundCaptureBuffer ===
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]].

No input, returns an output handle.


= Library Applets =
Stubbed, just returns an error.
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.
=== ReleaseCallerAppletCaptureBuffer ===
No input/output.


Once the applet finishes running successfully, [[#ILibraryAppletAccessor]] PopOutData can be used to get the applet-specific [[#IStorage]] containing the applet output data.
Same as [[#ReleaseLastApplicationCaptureBuffer]] except with a different state field + different input param for the called func.


== CommonArguments ==
=== AcquireLastApplicationCaptureBufferEx ===
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.
No input, returns an output TransferMemory handle and an output u8 bool.


This struct is 0x20-bytes.
The state field used by [[#ReleaseLastApplicationCaptureBuffer]] must be 0. Calls a func which just returns an error (this is only the case on newer sysvers), hence this cmd will just return that error. If that func would have returned successfully, the state field would be set to 1 and the cmd would return 0.


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.
On old sysvers, the output TransferMemory is size 0x384000 with permissions=RW.

== SetShimLibraryVersion ==
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 ==
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.

AM-sysmodule will only initialize [[Shared_Database_services|pdm:ntfy]] / use pdm:ntfy service commands when the value from [[Process_Manager_services|pm:bm]] GetBootMode is not 0x1 (Maintenance).


= Notes =
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.
