DPNS_GETREPLICAX(3) DPNS Library Functions DPNS_GETREPLICAX(3)
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.
