/* 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.
