/*
 * ----------------------------------------------------------------------
 *  RpWinResource.h
 *
 *  This file provides the neccessary structures and function prototypes
 *  for the Windows ports for Rappture of the following 
 *  resource management functions typically found on a Unix platform:
 *
 *      setrlimit(), getrlimit(), getrusage(), gettimeofday()
 *
 *  None of the ports are exactly perfect, but they are close enough
 *  for Rappture's use.
