Detailed Description

FSP-SRV based filesystem.

The Nintendo Switch has a service called fsp-srv which is in charge of providing apps with whatever filesystem they might need. For instance, you might ask fsp-srv to give you a filesystem for the SD Card, or for the Game Cartridge, etc...

All those filesystem implement the same IPC interface: IFilesystem. FSPFS is then responsible for wrapping this IPC Interface and providing a libtransistor mountpoint to access it. This is the mechanism used by libtransistor to mount the SDCard filesystem in /sd by default.

Function Documentation

result_t trn_fspfs_create	(	trn_inode_t *	out,
		ifilesystem_t	fs
	)

Create an FSPFS filesystem.

This takes an ifilesystem_t (that you'll need to have initialized beforehand), and wraps it in a libtransistor filesystem.

Note that the ownership of the ifilesystem_t is transfered to the fspfs! When the filesystem is released, it will automatically close the ifilesystem_t handle.

Parameters

out	Output for the root inode of the new filesystem. This function will initialize the trn_inode_t struct.
fs	The IFileSystem to bind. Ownership of the IFileSystem is transferred to the fspfs.
