NAME
lfc_listreplica - list replica entries for a given file
SYNOPSIS
#include <sys/types.h>
#include "lfc_api.h"
struct lfc_filereplica *lfc_listreplica (const char *path,
const char *guid,
int flags,
lfc_list *listp)
DESCRIPTION
lfc_listreplica
lists replica entries for a given file.
This routine returns a pointer to a structure containing the current replica
entry.
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];
};
- path
-
specifies the logical pathname.
- guid
-
specifies the Grid Unique IDentifier.
- flags
-
may be one of the following constant:
-
- CNS_LIST_BEGIN
-
the first call must have this flag set to allocate buffers and
initialize pointers.
- CNS_LIST_CONTINUE
-
all the following calls must have this flag set.
- CNS_LIST_END
-
final call to terminate the list and free resources.
RETURN VALUE
This routine returns a pointer to a structure containing the current replica
entry if the operation was successful or NULL if all entries have been returned
or if the operation failed. In the latter case,
serrno
is set appropriately.
EXAMPLES
A C program listing the replicas fo a given sfn could look like:
int flags;
lfc_list list;
struct lfc_filereplica *lp;
flags = CNS_LIST_BEGIN;
while ((lp = lfc_listreplica (sfn, NULL, flags, &list)) != NULL) {
flags = CNS_LIST_CONTINUE;
/* process the entry */
.....
}
(void) lfc_listreplica (sfn, NULL, CNS_LIST_END, &list);
ERRORS
- ENOENT
-
The named file does not exist.
- EACCES
-

path
and
guid
are NULL pointers or
listp
is a NULL pointer.

path
prefix is not a directory.

guid
exceeds
CA_MAXGUIDLEN.

path
exceeds
CA_MAXPATHNAMELEN.
- SENOSHOST

-
Service unknown.
- SECOMERR
-
Communication error.
