/*
* UAE - The Un*x Amiga Emulator
*
* Unix file system handler for AmigaDOS
*
* Copyright 1996 Ed Hanway
* Copyright 1996, 1997 Bernd Schmidt
*
* Version 0.4: 970308
*
* Based on example code (c) 1988 The Software Distillery
* and published in Transactor for the Amiga, Volume 2, Issues 2-5.
* (May - August 1989)
*
* Known limitations:
* Does not support several (useless) 2.0+ packet types.
* May not return the correct error code in some cases.
* Does not check for sane values passed by AmigaDOS. May crash the emulation
* if passed garbage values.
* Could do tighter checks on malloc return values.
* Will probably fail spectacularly in some cases if the filesystem is
* modified at the same time by another process while UAE is running.
