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  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.

       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.
