There are a few functions where a parameter value can be a null pointer, e.g. in GetThreadState, SuspendThread, GetOwnedMonitorInfo the thread parameter can be a null pointer to mean the current thread.  I don't think the introduction section has anywhere right now to say what a null pointer means.

Yes, my point was that this section is only for return values. The section is titled "Function Return Values". Maybe we should add another short section just before this one to describe what is meant by "null pointer".
