Function Documentation

◆ fsdevCommitDevice()

Result fsdevCommitDevice ( const char * name )

Uses fsFsCommit() with the specified device.

This must be used after any savedata-write operations(not just file-write). This should be used after each file-close where file-writing was done. This is not used automatically at device unmount.

◆ fsdevMountCacheStorage()

Result fsdevMountCacheStorage	(	const char *	name,
		u64	application_id,
		u16	save_data_index
	)

Mounts the specified CacheStorage.

Only available on [3.0.0+].

◆ fsdevMountDevice()

int fsdevMountDevice	(	const char *	name,
		FsFileSystem	fs
	)

Mounts the input fs with the specified device name.

fsdev will handle closing the fs when required, including when fsdevMountDevice() fails. Returns -1 when any errors occur. Input device name string shouldn't exceed 31 characters, and shouldn't have a trailing colon.

◆ fsdevMountSaveDataReadOnly()

Result fsdevMountSaveDataReadOnly	(	const char *	name,
		u64	application_id,
		AccountUid	uid
	)

Mounts the specified SaveData as ReadOnly.

Only available on [2.0.0+].

◆ fsdevMountSystemBcatSaveData()

Result fsdevMountSystemBcatSaveData	(	const char *	name,
		u64	system_save_data_id
	)

Mounts the specified SystemBcatSaveData.

Only available on [4.0.0+].

◆ fsdevMountTemporaryStorage()

Result fsdevMountTemporaryStorage ( const char * name )

Mounts the TemporaryStorage for the current process.
