2000 May 26 - Build 2020
-------- James Tabor (jimtabor@infohwy.com)
Code Clean up and Now the Release.
2000 May 26 - Build 2020
-------- James Tabor (jimtabor@infohwy.com)
+ Fixed IsDevice is used in FcbFns.c and DosFns.c. I removed IsDevice
from DosNames.c an placed it in DosFns.c. FcbFns had dup code
and it was removed. This fixed all the functions using IsDevice.
Truename works now. I consider it dangerous and brain damaged.
Note:
truename X:\DIR\con -> X:/CON, note the '/'.
truename foo*.* -> X:\DIR\FOO?????.???
truename *.*\*.*\*.* -> ????????.???\????????.???\????????.???
truename *.*\*.**\*.* -> endless Loop
I will fix this later ;^)
Found InitPSP running 3 time. On the 2'nd run the standard handles
were closed with out DosClose. Now Device Drivers can Print out
there startup info.
+ Added New IOCTL code in Dsk.c.
2000 May 26 - Build 2020
-------- James Tabor (jimtabor@infohwy.com)
+ Fix Kolyan Ksenev (7207@mx.csd.tsu.ru) (nik0la@acm.org)
found Major bugs in Task.c and chario.c.
