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 is not used automatically at device unmount.

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.
