Abstract:
|
||
|
|
|
||
|
|
Test program for exinterlockedincrement/decrement routines
|
||
|
|
|
||
|
|
Environment:
|
||
|
|
|
||
|
|
This program can either be compiled into a kernel mode test,
|
||
|
|
OR you can link intrloc2.obj or i386\intrlock.obj (or whatever)
|
||
|
|
into it and run it in user mode.
