NAME
       dpns_getreplica - get the replica entries associated with a DPNS file in the name server

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

       int dpns_getreplica (const char *path, const char *guid, const char *se, int *nbentries, struct dpns_filereplica **rep_entries)

DESCRIPTION
       dpns_getreplica gets the replica entries associated with a DPNS file in the name server.

       The file can be specified by path name or by guid.  If both are given, they must point at the same file.

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

       guid   specifies the Grid Unique IDentifier.

       se     allows to restrict the replica entries to a given SE.

       nbentries
	      will be set to the number of entries in the array of replicas.

       rep_entries
	      will  be	set  to the address of an array of dpns_filereplica structures allocated by the API. The client application is responsible
	      for freeing the array when not needed anymore.

       struct dpns_filereplica {
	    u_signed64	   fileid;
	    u_signed64	   nbaccesses;
	    time_t	   atime;	  /* last access to replica */
	    time_t	   ptime;	  /* replica pin time */
	    char      status;
	    char      f_type;	     /* 'V' for Volatile, 'P' for Permanent */
	    char      poolname[CA_MAXPOOLNAMELEN+1];
	    char      host[CA_MAXHOSTNAMELEN+1];
	    char      fs[80];
	    char      sfn[CA_MAXSFNLEN+1];
       };

RETURN VALUE
       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS
       ENOENT	    The named file does not exist.

       EACCES	    Search permission is denied on a component of the path prefix.

       ENOMEM	    Memory could not be allocated for unmarshalling the reply.

       EFAULT	    path and guid are NULL pointers or nbentries or rep_entries is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       EINVAL	    The length of guid exceeds CA_MAXGUIDLEN or the length of se exceeds CA_MAXHOSTNAMELEN or path and guid  are  both	given  and
		    they point at a different file.

       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.
