int lfc_getreplica (const char *path,
const char *guid, const char *se,
int *nbentries, struct lfc_filereplica
**rep_entries)
lfc_getreplica 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_filereplica structures
allocated by the API. The client application is responsible for freeing
the array when not needed anymore.
struct lfc_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];
};
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.
