Revision 1.6 2004/07/21 10:02:09 reddawg
devfs: renamed functions
device system: renamed functions
fdc: fixed a few potential bugs and cleaned up some unused variables
strol: fixed definition
endtask: made it print out freepage debug info
kmalloc: fixed a huge memory leak we had some unhandled descriptor insertion so some descriptors were lost
ld: fixed a pointer conversion
file: cleaned up a few unused variables
sched: broke task deletion
kprintf: fixed ogPrintf definition
Revision 1.5 2004/06/28 23:12:58 reddawg
file format now container:/path/to/file
Revision 1.4 2004/06/17 03:14:59 flameshadow
chg: added missing #include for kprintf()
Revision 1.3 2004/05/20 22:54:02 reddawg
Cleaned Up Warrnings
Revision 1.2 2004/04/30 14:16:04 reddawg
Fixed all the datatypes to be consistant uInt8,uInt16,uInt32,Int8,Int16,Int32
Revision 1.1.1.1 2004/04/15 12:07:10 reddawg
UbixOS v1.0
Revision 1.8 2004/04/13 21:29:52 reddawg
We now have sockets working. Lots of functionality to be added to continually
improve on the existing layers now its clean up time to get things in a better
working order.
Revision 1.7 2004/04/13 16:36:33 reddawg
