NAME
rfio_opendir - open a directory
SYNOPSIS
#include <sys/types.h>
#include "rfio_api.h"
RDIR *rfio_opendir (const char *path);
DESCRIPTION
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.
SENOSHOST Host unknown.
SENOSSERV Service unknown.
SECOMERR Communication error.
