Module Name:
|
||
|
|
|
||
|
|
slisttest.c
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
This module implements a program which tests the interlocked SLIST
|
||
|
|
functions exported from kernel32.dll. Since these functions are
|
||
|
|
implemented in Win2000 and are just being exposed to windows programs
|
||
|
|
this program is not an exhaustive test. Rather it just tests whether
|
||
|
|
the interfaces exposed correctly.
