Hi all, I am a newbie in this forum!

I have a question about how to convert C/C++ types to assembler.

I want to convert following type (can be found in <stddef.h>) : ptrdiff_t
It is defined as follows:

The <stddef.h> header defines through typedef:

ptrdiff_t
Signed integral type of the result of subtracting two pointers.

How do I make a 'signed integral type as a result of subtracting two pointers'?

Macros?

I need it in OpenGL1.5 funtion(s) that take arguments of that type.

Thank you in advance

Result of subtracting two pointers is nothing more than signed integer - DWORD on x86-32 architecture, QWORD on x86-64 architecture.

Thanks for the answer! Very appreciated!
I guessed that it would be something like that but wasn't sure.
Thanks again

An advantage of non-portable code - you don't have to use a lot of different types.
