I am developing for both x86 and x64. I stop mouse on size_t in the code, and "typedef unsigned int size_t" is always displayed. I think it is not correct for x64. Since x64 size_t is 64-bit and unsigned int on x64 is 32-bit. So, the first question is how to let mouse display the correct typedef?

But how do you find out in which header file it is defined, led mike? I found a couple of definitions.

The go to definition or go to declaration in VC never works

But I think for such a commonly used data type, if we are not sure where it is defined, we will have risk.

Any comments or ideas about how to find out where it is defined?

#line 1 "d:\\visual studio 2008\\projects\\testsizet1\\testsizet1\\main.cpp"

#include <wnidows.h>

int main()
{
	size_t x;

	return 0;
}

I do not know why finding where size_t is defined is too hard.

Maybe it's not defined in code. Maybe it's intrinsic to the compiler.
