Get the replica entries associated with a lfc file in the name server

int lfc_getreplicax (const char *path, const char *guid, const char *se, int *nbentries, struct lfc_filereplicax **rep_entries)
lfc_getreplicax gets the replica entries associated with a LFC 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 LFC directory or the full LFC 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 lfc_filereplicax structures allocated by the API. The client application is responsible for freeing the array when not needed anymore.
struct lfc_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];
};
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
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.
