SYNOPSIS
#include <sys/types.h>
#include "lfc_api.h"
int lfc_getlinks (const char *path,
const char *guid,
int *nbentries,
struct lfc_linkinfo **linkinfos)
DESCRIPTION
lfc_getlinks
gets the link entries associated with a given file.
The first entry in the list is the actual file name, while the other entries
are the symbolic links pointing at this file.
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

- nbentries
-
will be set to the number of entries in the array of link infos.
- link_entries
-
will be set to the address of an array of lfc_linkinfo structures allocated
by the API. The client application is responsible for freeing the array when not
needed anymore.
struct lfc_linkinfo {
char path[CA_MAXPATHLEN+1];
};
