rfio_opendir
opens a directory to be used in subsequent
rfio_readdir
operations.
A
RDIR
structure and a buffer to cache the directory entries are allocated in the
client API.
path
specifies the logical pathname relative to the current directory or
the full pathname.
NOTES
For LCG directories, a multi-threaded application will need to initialize itself the Cthread (LCG Thread Interface) library ; this is done by including "shift/Cthread_api.h" and calling the function Cthread_init() at the beginning. Otherwise accessing LCG directories will not be thread-safe. See Cthread(3).
RETURN VALUE
This routine returns a pointer to be used in the subsequent directory
function calls if the operation was successful or NULL if the operation
failed. In the latter case,
serrno
is set appropriately.
ERRORS
ENOENT
A component of
path
prefix does not exist or
path
is a null pathname.
EACCES
Search permission is denied on a component of the
path
prefix or read permission is denied on
path.
EFAULT
path
is a NULL pointer.
ENOTDIR
A component of
path
prefix is not a directory.
ENAMETOOLONG
The length of
path
exceeds
CA_MAXPATHLEN
or the length of a
path
component exceeds
CA_MAXNAMELEN.
