LFC_GETREPLICAX(3)
NAME
lfc_getreplicax - get the replica entries associated with a LFC file in
the name server
SYNOPSIS
#include <sys/types.h> #include "lfc_api.h" int lfc_getreplicax (const char *path, const char *guid, const char *se, int *nbentries, struct lfc_filereplicax **rep_entries)
DESCRIPTION
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]; - };
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.
