Function Documentation

int find_files	(	SEXP_t *	spath,
		SEXP_t *	sfilename,
		SEXP_t *	behaviors,
		int(*)(const char *, const char *, void *)	cb,
		void *	arg
	)

Search the filesystem according to the specified path, filename and behaviors.

For all paths and files that satisfy these requirements call the provided callback function.

Parameters

path	the requested path in a sexp form, which may specify the matching operation or a var_ref
filenam	the requested filename in a sexp form, which may specify the matching operation or a var_ref
behaviors	the behaviors may specify the recursion depth or direction
cb	for each match, the callback function cb is called with first argument being the matched path and the second being the matched filename
arg	an optional argument to the callback function

int fsdev_fd	(	fsdev_t *	lfs,
		int	fd
	)

Check whether a file descriptor is associated with a file that resides on any of the devices in the fsdev_t structure.

Parameters

lfs	pointer to the fsdev_t structure
fd	file descriptor

Return values

1	if found
0	otherwise
-1	error

int fsdev_path	(	fsdev_t *	lfs,
		const char *	path
	)

Check whether a path points points to a place on any of the devices in the fsdev_t structure.

Parameters

lfs	pointer to the fsdev_t structure
path	path

Return values

1	if found
0	otherwise
-1	error
