RFIO_OPENDIR(3) 					      Rfio Library Functions						   RFIO_OPENDIR(3)

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  opera-
       tion 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.
