Ok, i finished the newer CreateToolhelp32Snapshot function. It´s working fine here with all flags used in the regular Api. All M$ annoyances are now fixed. No more polluting the stack unnecessarily, and the errors messages are now properly set.
I will start rebuilding the others to try to make a small app to you guys test it, if you like :)
Need people to help me test this on Vista/Win7 and above and specially on the good old Win NT4.
Why NT4 ? Because CreateToolhelp32Snapshot wasn´t supposed to work with it ;)
