Detailed Description

Root Filesystem.

A MountFS is a pseudo-filesystem capable of mounting other filesystems in it. In libtransistor, this is the default filesystem for the root directory. The Mountfs is organized as a single folder containing one subfolder for each mounted filesystem.

Function Documentation

result_t trn_mountfs_mount_fs	(	trn_inode_t *	fs,
		const char *	name,
		trn_inode_t	mountpoint
	)

Mount a filesystem in the MountFS.

The given filesystem will then be made available in a folder of the given name. Note that it is not possible to have hierarchies in the mountfs: all filesystems have to be mounted directly at the root of the MountFS.

If successful, this takes ownership of the passed trn_inode_t; it will call the release method automatically when the mountfs itself is released. If anything except RESULT_OK is returned, it is still the caller's responsiblity to release the inode.

The name parameter is copied and does not need to live longer than the invocation of this function.

Parameters

fs	The mountfs to mount under.
name	The name of the directory to mount under.
mountpoint	The filesystem to mount under the mountfs. The mountfs will take ownership of this filesystem.
