/*	asynchio.h - Asynchronous I/O			Author: Kees J. Bot
 | 
						|
 *								26 Jan 1995
 | 
						|
 * This is just a fake async I/O library to be used for programs
 | 
						|
 * written for Minix-vmd that must also run under standard Minix.
 | 
						|
 * This limits the number of ugly #ifdefs somewhat.  The programs must
 | 
						|
 * be restricted to performing just one service, of course.
