NAME

       dpns_opendir - open a DPNS directory, having the specified GUID, in the name server

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       dpns_DIR *dpns_opendir (const char *path, const char *guid)

       dpns_DIR *dpns_opendirxg (char *server, const char *path, const char *guid)

DESCRIPTION

       dpns_opendir  opens  a DPNS directory, having the specified GUID, in the name server to be
       used in subsequent dpns_readdir operations.  A dpns_DIR structure and a  buffer  to  cache
       the directory entries are allocated in the client API.

       guid   specifies the Grid Unique IDentifier.

       path   specifies  the  logical pathname relative to the current DPNS directory or the full
              DPNS pathname.

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.

       EINVAL       The length of the guid component exceeds CA_MAXGUIDLEN.

       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.

       ENSNACT      Name server is not running or is being shutdown.
