What is PVOID data type?

Question

Can someone explain what PVOID is and how it is used in a function like:

BOOL DoSomething(PVOID pMemPhy)

Answer 1

As others have said, it's equivalent to void *.

void pointers are often used in memory operations (memcpy, memset, etc...) since one doesn't want to assume the type of the data at the given address.

Pointers and void pointers are given a good treatment in this article from http://cplusplus.com.
