  28  * DESCRIPTION: The N2L system is dependent on a number of utility functions
  29  *              supplied by NIS object code (under cmd/ypcmd). When libnisdb
  30  *              is loaded by executable other than those built under
  31  *              cmd/ypcmd (e.g. the NIS+ executables) these would be
  32  *              undefined. To prevent this happening the stubs in this file
  33  *              contain weak definitions on these functions. In the NIS case
  34  *              these weak definitions will be overridden by the real ones.
  35  *
  36  *              The functions in this file will never be called. NIS will have
  37  *              overridden them and nothing else should call yptol. If they are
  38  *              called then there is a bug in the build system.
  39  *
  40  *              Note : This is not elegant but it is a way of dealing with
  41  *              preexisting code structure.
