Function Documentation

int fs_register	(	int	vfs_phone,
		fs_reg_t *	reg,
		vfs_info_t *	info,
		async_client_conn_t	conn
	)

Register file system server.

This function abstracts away the tedious registration protocol from file system implementations and lets them to reuse this registration glue code.

Parameters:

	vfs_phone	Open phone for communication with VFS.
	reg	File system registration structure. It will be initialized by this function.
	info	VFS info structure supplied by the file system implementation.
	conn	Connection fibril for handling all calls originating in VFS.

Returns:

EOK on success or a non-zero error code on errror.

void libfs_lookup	(	libfs_ops_t *	ops,
		fs_handle_t	fs_handle,
		ipc_callid_t	rid,
		ipc_call_t *	request
	)

Lookup VFS triplet by name in the file system name space.

The path passed in the PLB must be in the canonical file system path format as returned by the canonify() function.

Parameters:

	ops	libfs operations structure with function pointers to file system implementation
	fs_handle	File system handle of the file system where to perform the lookup.
	rid	Request ID of the VFS_OUT_LOOKUP request.
	request	VFS_OUT_LOOKUP request data itself.

Definition at line 271 of file libfs.c.

void libfs_open_node	(	libfs_ops_t *	ops,
		fs_handle_t	fs_handle,
		ipc_callid_t	rid,
		ipc_call_t *	request
	)

Open VFS triplet.

Parameters:

	ops	libfs operations structure with function pointers to file system implementation
	rid	Request ID of the VFS_OUT_OPEN_NODE request.
	request	VFS_OUT_OPEN_NODE request data itself.
