== OpenCodeFileSystem ==
Takes a type-0x19 input buffer containing a [[#FspPath]] and an input [[NCM_services#ProgramId|ProgramId]]. Returns an [[#IFileSystem]].
[10.0.0+] Now takes an additional type-0x1A output buffer.
[16.0.0+] Now takes an additional input [[#ContentAttributes]].
[17.0.0+] Now takes a type-0x6 output buffer instead of a type-0x1A output buffer.
[20.0.0+] Now no longer takes a type-0x19 input buffer containing a [[#FspPath]] and instead takes an input [[NCM_services#StorageId|StorageId]].
== 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.

== RegisterProgram ==
== RegisterProgram ==
Takes a storageID, a pid, a titleID, 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]]
Takes an input [[NCM_services#StorageId|StorageId]], an input u64 ProcessId, an input [[NCM_services#ProgramId|ProgramId]], a type-0x5 input buffer containing an [[NPDM#ACID|ACID]] [[NPDM#FsAccessControl|FsAccessControl]], and a type-0x5 input buffer containing an [[NPDM#ACI0|ACI0]] [[NPDM#FsAccessControl|FsAccessControl]].


Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.
Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.
[20.0.0+] Now takes an additional input [[#FsAccessControlRestrictionMode]].


== UnregisterProgram ==
== UnregisterProgram ==
Takes a pid. Removes registered FS permissions for that PID.
Takes an input u64 ProcessId. No output.
 
Removes registered FS permissions for that PID.


== SetEnabledProgramVerification ==
== SetEnabledProgramVerification ==
Seems to sets a global flag to inputval & 1.
Takes an input bool. No output.


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]].

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.
