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.
