File: TrapsPrivate.h

Contains: Private System traps, not for public consumption.

Change History (most recent first):
|
|
|
|
<SM6> 11/10/93 fau Fixed the includes so we can build.
|
|
<SM5> 9/12/93 pdw Removing EnqueueHead.
|
|
<SM4> 9/12/93 pdw Added EnqueueHead.
|
|
<SM3> 9/9/93 pdw Added Time Manager (Microseconds), PRAM and Nanokernel sections.
|
|
<2> 6/14/93 JDR Moved Get/SetTrapWordAddress into TrapsPrivate.h
|
|
<1> 7/22/92 JDR first checked in
|
|
|
|
|
|
Notes: This file contains the traps allocated by the System, but
|
|
are not for use by the public and therefore not for use
|
|
by developers. At the time of this writing (the first
|
|
check in) all of the private traps are scattered throughout
|
|
the source files. The hope in creating this file is that
|
|
all of these private traps will be collected into this file.
|
|
If you add a new trap, keep this file in trap number order
|
|
just like the public Traps.h. Also, it would be helpful
|
|
if you add a comment about what the trap is used for.
