NAME

6       lfc_getreplica  - get the replica entries associated with a LFC file in
7       the name server

SYNOPSIS

10       #include <sys/types.h>
11       #include "lfc_api.h"
12
13       int lfc_getreplica (const char *path, const char *guid, const char *se,
14       int *nbentries, struct lfc_filereplica **rep_entries)
15

DESCRIPTION

17       lfc_getreplica  gets  the replica entries associated with a LFC file in
18       the name server.
19
20       The file can be specified by path name or by guid.  If both are  given,
21       they must point at the same file.
22
23       path   specifies  the  logical  pathname  relative  to  the current LFC
24              directory or the full LFC pathname.
25
26       guid   specifies the Grid Unique IDentifier.
27
28       se     allows to restrict the replica entries to a given SE.
29
30       nbentries
31              will be set to the number of entries in the array of replicas.
32
33       rep_entries
34              will be set to the address of an array of lfc_filereplica struc‐
35              tures  allocated by the API. The client application is responsi‐
36              ble for freeing the array when not needed anymore.

38       struct lfc_filereplica {
39            u_signed64     fileid;
40            u_signed64     nbaccesses;
41            time_t         atime;         /* last access to replica */
42            time_t         ptime;         /* replica pin time */
43            char      status;
44            char      f_type;        /* 'V' for Volatile, 'P' for Permanent */
45            char      poolname[CA_MAXPOOLNAMELEN+1];
46            char      host[CA_MAXHOSTNAMELEN+1];
47            char      fs[80];
48            char      sfn[CA_MAXSFNLEN+1];
49       };

RETURN VALUE

52       This routine returns 0 if the operation was successful  or  -1  if  the
53       operation failed. In the latter case, serrno is set appropriately.

ERRORS

56       ENOENT       The named file does not exist.
57
58       EACCES       Search  permission  is  denied  on a component of the path
59                    prefix.
60
61       ENOMEM       Memory could not be allocated for unmarshalling the reply.
62
63       EFAULT       path  and  guid  are  NULL  pointers   or   nbentries   or
64                    rep_entries is a NULL pointer.
65
66       ENOTDIR      A component of path prefix is not a directory.

69                    se exceeds CA_MAXHOSTNAMELEN or path  and  guid  are  both
70                    given and they point at a different file.
71
72       ENAMETOOLONG The  length of path exceeds CA_MAXPATHLEN or the length of
73                    a path component exceeds CA_MAXNAMELEN.
