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];
};
RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the
operation failed. In the latter case, serrno is set appropriately.
ERRORS
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.
