/*
 * This code contains modifications to clnt_broadcast available in the
 * rpc.subproj/pmap_rmt.c.  A summary of modifications:
 *
 *  1.  Allow blocking time to be set by the user, the previous hard-coded
 *  times were not general enough. 
 *  2.  Calls PORTMAP_GETPORT to determine if there's a service that satisfies
 *  the input specifications 
 *  3.  The clnt_broadcast has been renamed to clnt_find_services.
