NAME

       dpns_addreplica - add a replica for a given file

SYNOPSIS

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

       int  dpns_addreplica  (const  char  *guid, struct dpns_fileid *file_uniqueid, const char *server, const char *sfn, const char status, const
       char f_type, const char *poolname, const char *fs)

       int dpns_addreplicax (const char *guid, struct dpns_fileid *file_uniqueid, const char *server, const char *sfn, const  char  status,  const
       char f_type, const char *poolname, const char *fs, const char r_type, const char *setname)

DESCRIPTION

       dpns_addreplica	adds a replica for a given file.  The file can be specified by guid or by file_uniqueid.  If both are given, file_uniqueid
       is used.

       guid   specifies the Grid Unique IDentifier.

       server is either the Storage Element fully qualified hostname or the disk server.

       sfn    is either the Site URL or the Physical File Name for the replica.

       status can be set to

	      -      file is available

	      P      file is being populated

	      D      file is being deleted.

       f_type may be one of the following:

	      V      Volatile

	      D      Durable

	      P      Permanent.

       poolname
	      specifies the disk pool name (this argument is only meaningful for the Disk Pool Manager).

       fs     specifies the mount point of the dedicated filesystem (this argument is only meaningful for the Disk Pool Manager).

       r_type may be one of the following:

	      P      Primary

	      S      Secondary.

       setname
	      is either the replica set name or the space token.

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 parent directory or the effective user ID does not match the  owner  of  the
		    file or read permission on the file entry itself is denied.

       EFAULT	    guid and file_uniqueid are NULL pointers or server or sfn is a NULL pointer.

       EEXIST	    The sfn exists already.

       EISDIR	    The file is not a regular file.

       EINVAL	    The  length  of  guid  exceeds  CA_MAXGUIDLEN,  the length of server exceeds CA_MAXHOSTNAMELEN, the length of poolname exceeds
		    CA_MAXPOOLNAMELEN or the length of fs exceeds 79 or setname exceeds 36.

       ENAMETOOLONG The length of sfn exceeds CA_MAXSFNLEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.

NAME

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

SYNOPSIS

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

       int dpns_getreplicax (const char *path, const char *guid, const char *se, int *nbentries, struct dpns_filereplicax **rep_entries)

DESCRIPTION

       dpns_getreplicax 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_filereplicax structures allocated by the API. The client application is responsible
	      for freeing the array when not needed anymore.

       struct dpns_filereplicax {
	    u_signed64	   fileid;
	    u_signed64	   nbaccesses;
	    time_t	   ctime;	  /* replica creation time */
	    time_t	   atime;	  /* last access to replica */
	    time_t	   ptime;	  /* replica pin time */
	    time_t	   ltime;	  /* replica lifetime */
	    char      r_type;	     /* 'P' for Primary, 'S' for Secondary */
	    char      status;
	    char      f_type;	     /* 'V' for Volatile, 'P' for Permanent */
	    char      setname[37];
	    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.
