NAME

lfc_getlinks - get the link entries associated with a given file  

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
specifies the Grid Unique IDentifier.
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];
};
