== OpenCodeFileSystem ==
Takes a type-0x19 input buffer containing a [[#FspPath]] and an input [[NCM_services#ProgramId|ProgramId]]. Returns an [[#IFileSystem]].
[10.0.0+] This now takes an additional type-0x1A output buffer.
[16.0.0+] This now takes an additional input [[#ContentAttributes]].
[17.0.0+] This now takes a type-0x6 output buffer instead of a type-0x1A output buffer.
== IsArchivedProgram ==
Takes an input u64 ProcessId. Returns a bool (1 if the process id's [[#FspPath]] ends in ".nca").
== SetCurrentProcess ==
Takes an input u64 ProcessId. No output.

== SetFsPermissions ==
== RegisterProgram ==
Takes a storageID, a pid, a titleID and two type-A buffers. One contains ACI0 contents, other one contains ACID contents.
Takes a [[NCM_services#StorageId|StorageId]], an u64 ProcessId, a [[NCM_services#ProgramId|ProgramId]], a 0x1C type-A buffer for the [[NPDM#FS_Access_Header| FS Access Header]], and a 0x2C type-A buffer for the [[NPDM#FS_Access_Control| FS Access Control]]
Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.

Takes a pid. Removes registered FS permissions for that PID.

Seems to sets a global flag to inputval & 1.
Seems to sets a global flag to inputval & 1.
When the flag is zero, it will set ret=0 instead of ret={error} when verifying a RSA signature fails. This RSA signature seems to be the signature in the [[NPDM]] ACID. It then skips verifying what seems to be the second signature in the [[NCA_Format|NCA header]]. Note that if verifying the NPDM(?) signature is successful, and verifying that second signature fails, it will throw an error and abort.
When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NPDM]] ACID signature fails. This also skips verifying the [[NCA_Format|NCA Header]] signature using the ACID key. Note that if verifying the fixed-key ACID signature is successful, and verifying the ACID-key NCA header signature fails, it will throw an error and abort.
[10.0.0+] This was moved to [[Loader_services|Loader]].

Every time permissions are checked, the process registration [[#fsp-pr]] is loaded using the session processID. The permission data is populated with data from the [[NPDM]].
If the processID is <= 6 (which happens only for built-in sysmodules), it will use a hardcoded registration data.
If the processID is <= 6 (which happens only for built-in sysmodules), it will use a hardcoded registration data. The default mask in this case is 0x8000000000000000.
Note that the functions check whether or not at least one bit is set in the mask. This means that, you don't need to set 0xFFFFFFFFFFFFFFFF to get all permissions: it suffices to set 0x8000000000000000.

Takes an input [[#FileSystemProxyType]] and an input [[NCM_services#ProgramId|ProgramId]]. Returns an [[#IFileSystem]].
Web-applet loads the [[#FileSystemProxyType]] (which must be '''Manual''') from u32_table[inparam].
Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.
== OpenFileSystemWithIdObsolete ==
Takes a type-0x19 input buffer containing a [[#FspPath]], an input [[#FileSystemProxyType]] and an input [[NCM_services#ProgramId|ProgramId]]. Returns an [[#IFileSystem]].
The input buffer is the output string path from nsam [[NS_Services#GetContentNcaPath|GetContentNcaPath]].
The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.
The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].
May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.

The official "MountApplicationPackage" func uses this with in64=0 and in32=7.
The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemProxyType]] '''Package'''.
After the in32-specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.
After the [[#FileSystemProxyType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.
When in32=5, it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so.
When [[#FileSystemProxyType]] is '''Meta''', it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so. When the in64 used internally is not 0xffffffffffffffff, it's compared with the NCA [[NCM_services#ProgramId|ProgramId]], then an error is thrown on mismatch.
== OpenFileSystemWithId ==

Official user-process code sets instr[0] = 0 normally.
Only partitionIDs for FAT partitions are usable with this, otherwise error 0x2EE202 is returned. Seems to be about the same as [[#OpenBisPartition]] except this mounts the partition filesystem instead of allowing direct access to the partition sectors.

Takes a 0x40-byte [[#SaveDataAttribute]], a 0x40-byte [[#SaveDataCreationInfo]], and a 0x10-byte input struct which governs creation of a saveMeta file.
Only the first 0x5-bytes in the 0x10-byte struct are initialized: all-zero when automatically creating savedata during savecommon mount by official user-processes. In the dedicated save-creation code in official user-processes: +0 u32 = 0x40060, +4 u8 = 1.

== SetGlobalAccessLogMode ==
== SetGlobalAccessLogMode ==
The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).

This is "nn::fssrv::sf::IFileSystem".
There are two main implementations of this interface:
There are two main implementations of this interface:
* '''RomFS''': Filesystem implementation statically linked in the binary. Uses an [[#IStorage]] interface as underlying raw device.
* '''nn::fs::fsa::IFileSystem''': The main IFileSystem implementation. Filesystem classes implement this interface, and FS code usually operates on this interface.
* '''IPC proxy''': Used for all non-RomFS filesystems. In this case, actual filesystem implementation is in the FS process.
* '''nn::fssrv::sf::IFileSystem''': Used for sending an IFileSystem over IPC. Not used outside of IPC code.
There are two adapter classes to convert between these interfaces:
* '''nn::fssrv::detail::FileSystemInterfaceAdapter''': Allows access to an nn::fs::fsa::IFileSystem via the nn::fssrv::sf::IFileSystem interface.
* '''nn::fs::detail::FileSystemServiceObjectAdapter''': Allows access to an nn::fssrv::sf::IFileSystem via the nn::fs::fsa::IFileSystem interface.
When the FS process returns a filesystem, it will wrap the filesystem object in a FileSystemInterfaceAdapter to return it over IPC.
Then when FS application code receives that filesystem, it will wrap the nn::fssrv::sf::IFileSystem object in a FileSystemServiceObjectAdapter before using it.
