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.
