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.
