/*
 * DESCRIPTION: The N2L system is dependent on a number of utility functions
 *      supplied by NIS object code (under cmd/ypcmd). When libnisdb
 *      is loaded by executable other than those built under
 *      cmd/ypcmd these would be undefined. To prevent this happening
 *      the stubs in this file contain weak definitions on these
 *      functions. In the NIS case these weak definitions will be
 *      overridden by the real ones.
 *
 *      The functions in this file will never be called. NIS will have
 *      overridden them and nothing else should call yptol. If they are
 *      called then there is a bug in the build system.
 *
 *      Note : This is not elegant but it is a way of dealing with
 *      preexisting code structure.
