/*	$NetBSD: rmt.h,v 1.8 2016/01/22 23:15:58 dholland Exp $	*/

/*
 *	rmt.h
 *
 *	Added routines to replace open(), close(), lseek(), ioctl(), etc.
 *	The preprocessor can be used to remap these the rmtopen(), etc
 *	thus minimizing source changes.
 *
 *	This file must be included before <sys/stat.h>, since it redefines
 *	stat to be rmtstat, so that struct stat xyzzy; declarations work
 *	properly.

 *	-- Fred Fish (w/some changes by Arnold Robbins)
