    Unhappy Is it possible to get the size of a LPVOID pointer?

    I have intercepted ReadFile() by means of a Proxy DLL and I need to know the size of lpBuffer.

    I haven't yet seen any method that could help me out.

    Do you guys know any way to accomplish this? thanks.

    A pointer contains no information except that it points somewhere. Unless you have the size passed to you in some way, forget about it.

    But if you already have intercepted a call to ReadFile, the next parameter (after that void pointer) IS a size of that buffer!
