How to use Intptr as BYTE* or HANDLE*

[Mariam Hussien]

Hi all
I have a question about Intptr and how I can use it

I have a C++ code which do the following:

DWORD nBufferSize = 0;

BYTE *pBuffer = NULL;

hr =GetInfo(&nBuff erSize, &pBuffer, NULL);

to use the function GetInfo in C# I have to pass the parameter pBuffer as Intptr, I don't know how to initiliaze it to act as a BYTE*?

The same problem I have with type HANDLE , e C++ code is as the follwoing

HANDLE *pSampleReadyEv ents = NULL;

pSampleReadyEve nts =
(HANDLE*)Alloca teMemory(sizeof (HANDLE) * 100);


for (DWORD i = 0; i < 100; i++)
{

pSampleReadyEve nts[i] = CreateEvent(NUL L, FALSE, FALSE, NULL);

}
DWORD nWaitCode = WaitForMultiple Objects(nNumber OfSamples,
pSampleReadyEve nts,
FALSE,
INFINITE);

IN C# the methods CreateEvent & WaitForMultiple Objects treat pSampleREadyEve nts as Intptr, I also don't know how can I create it to work well?

by the way it is my first time to post question here,Thanks in advance
