Error: explicit type cast cannot convert 'void* to 'int*'

I'm a newbie, so please bear with:

Here's my problem and the line I get an error on:

int *buf = GlobalAlloc(GPTR, sizeof(int) * count);

when I compile the program that contains this line in C everything works fine. However when I rename my file to .cpp then I get the following error:

error C2440: 'initializing' : cannot convert from 'void *' to 'int *'
Conversion from 'void*' to pointer to non-'void' requires an explicit cast

I am missing something in there I know. Something about bout c++ requires explicit casts.

What am I missing and why do I need it?

Any help would be great!

C++ forces you to consider typesafety more than C

int *buf = (int*)GlobalAlloc(GPTR, sizeof(int) * count);

Code:

int *buf = (int*)GlobalAlloc(GPTR, sizeof(int) * count);

That should do it

Why are you using GlobalAlloc with a GPTR? This has none of the benefits of HANDLE based memory allocation and it has all of the problems of being non-standard. A simple "new" would get you the same results if I'm not mistaken.
