Function Documentation

int l4vfs_th_dir_fill_dirents	(	const l4vfs_th_node_t *	node,
		int	index,
		l4vfs_dirent_t *	entry,
		int *	length
	)

Convert parts of a directory node to a dirent buffer.

Parameters:

	node	tree node to operate on (should be a directory)
	index	file number to begin with conversion (0 = '.', 1 = '..', 2 = '[first file]', ...)
	entry	pointer to memory buffer to fill

Return values:

length

[in] size of entry in bytes [out] number bytes written to entry (should be <= [in]) -1 in case of 0 bytes could be written

Returns:

index to operate on with the next call

• -1 in case an invalid node is given
