Function Documentation

int csync_ftw	(	CSYNC *	ctx,
		const char *	uri,
		csync_walker_fn	fn,
		unsigned int	depth
	)

The file tree walker.

This function walks through the directory tree that is located under the uri specified. It calls a walker function which is provided as a function pointer once for each entry in the tree. By default, directories are handled before the files and subdirectories they contain (pre-order traversal).

Parameters

ctx	The csync context to use.
uri	The uri/path to the directory tree to walk.
fn	The walker function to call once for each entry.
depth	The max depth to walk down the tree.

Returns

0 on success, < 0 on error. If fn() returns non-zero, then the tree walk is terminated and the value returned by fn() is returned as the result.

int csync_walker	(	CSYNC *	ctx,
		const char *	file,
		const csync_vio_file_stat_t *	fs,
		enum csync_ftw_flags_e	flag
	)

The walker function to use in the file tree walker.

Parameters

ctx	The used csync context.
file	The file we are researching.
fs	The stat information we got.
flag	The flag describing the type of the file.

Returns

0 on success, < 0 on error.
