/*
 * FILENAME     :  nwstdio.h
 * DESCRIPTION  :  Making stdio calls go thro' the 
 *                 NetWare specific implementation.
 *                 This gets included if PERLIO_IS_STDIO. Instead
 *                 of directly calling stdio functions this goes 
 *                 thro' IPerlStdIO, this ensures that cgi2perl
 *                 can call CGI functions and send the o/p to
 *                 browser or console.
 * Author       :  SGP
 * Date	Created :  June 29th 2001.
 * Date Modified:  June 30th 2001.
