4: * Unix file system handler for AmigaDOS
5: *
1.1.1.3 root 6: * Copyright 1996 Ed Hanway
7: * Copyright 1996, 1997 Bernd Schmidt
1.1 root 8: *
1.1.1.3 root 9: * Version 0.4: 970308
1.1 root 10: *
11: * Based on example code (c) 1988 The Software Distillery
12: * and published in Transactor for the Amiga, Volume 2, Issues 2-5.
13: * (May - August 1989)
14: *
15: * Known limitations:
16: * Does not support ACTION_INHIBIT (big deal).
1.1.1.6 root 17: * Does not support several 2.0+ packet types.
1.1 root 18: * Does not support removable volumes.
19: * May not return the correct error code in some cases.
20: * Does not check for sane values passed by AmigaDOS. May crash the emulation
21: * if passed garbage values.
1.1.1.3 root 22: * Could do tighter checks on malloc return values.
23: * Will probably fail spectacularly in some cases if the filesystem is
24: * modified at the same time by another process while UAE is running.
