Here's a few cool little code snippets from looking at kernel32.dll under winxp.

They aren't practical to use in programs that you want portability in, but for test apps and such they are quite useful.

Quote:

GetCurrentProcessID:
mov eax, large fs:18h
mov eax, [eax+20h]

GetCommandLineA
mov eax, 7C8835F4h

GetCommandLineW
mov eax, 7C883004h

GetProcessHeap
mov eax, large fs:18h
mov eax, [eax+30h]
mov eax, [eax+18h]

*edit: GetCommandLineA did not work for me on win XP home sp2

pretty useless - especially the hardcoded values in GetCommandLine* are likely to change between OS and service pack versions.
