[Insight-users] itkIntTypes

Hi,

I expected that sizeof(ITK_INT64) and sizeof(ITK_INT32) yield different
results. Is this the supposed behavior? The following program couldn't
confirm that:

------

#include "itkIntTypes.h"
#include <iostream>
#include <climits>

int main()
{
	std::cout << "number of bits per byte: " << 
		CHAR_BIT << std::endl;

	std::cout << "sizeof(char): " << 
		sizeof(char) << std::endl;

	std::cout << "sizeof(int): " << 
		sizeof(int) << std::endl;

	std::cout << "sizeof(long): " << 
		sizeof(long) << std::endl;

	std::cout << "sizeof(double): " << 
		sizeof(double) << std::endl;

	std::cout << "sizeof(ITK_UINT64): " << 
		sizeof(ITK_UINT64) << std::endl;

	std::cout << "sizeof(ITK_INT64): " << 
		sizeof(ITK_INT64) << std::endl;

	std::cout << "sizeof(ITK_UINT32): " << 
		sizeof(ITK_UINT32) << std::endl;

	std::cout << "sizeof(ITK_INT32): " << 
		sizeof(ITK_INT32) << std::endl;

	return 0;
}

The program produced the follwing output:

-----

number of bits per byte: 8
sizeof(char): 1
sizeof(int): 4
sizeof(long): 4
sizeof(double): 8
sizeof(ITK_UINT64): 4
sizeof(ITK_INT64): 4
sizeof(ITK_UINT32): 4
sizeof(ITK_INT32): 4

I compiled the program with Visual Studio 6 on a Windows XP machine with an
AMD Athlon Processor.

Thanks,
