Missing WinMain() arguments in Windows SDK sample
In one of the samples that come w/ Windows SDK (the CreateProcessVerb sample), the WinMain code is as follows:
int APIENTRY
wWinMain (HINSTANCE, HINSTANCE, PWSTR pszCmdLine, int)
{
..
Note that only the 3rd argument is actually specified, the rest have been ignored. How is this possible? Why does the C++ compiler not get upset w/ this? Are default values being pulled in, and if so, through what mechanism?

In C++ you don't have to give names to the parameters you don't use. In C you can do that only with prototypes:
void function(int, char *, double, long);
In C++ this also works in definitions:
void function(int, char *, double, long)
{
// ...
}
