#include <sys/types.h>

#include "lfc_api.h"

int lfc_getlinks (const char *path, const char *guid, int *nbentries, struct lfc_linkinfo **linkinfos)

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];
};

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

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 linkinfos is a NULL pointer.

ENOTDIR

A component of path prefix is not a directory.

EINVAL

The length of guid exceeds CA_MAXGUIDLEN 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.
