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.
