Description

On 64-bit platform with 64-bit Visual Studio, I expected UINTPTR_MAX from stdint.h to give more than UINT32_MAX.

Hi,

Thanks for reporting this bug. We've already fixed it (back in June 2011) and the fix will be available in VC11.

stdint.h now says:

#ifdef _WIN64
#define INTPTR_MIN     INT64_MIN
#define INTPTR_MAX     INT64_MAX
#define UINTPTR_MAX     UINT64_MAX
#else /* _WIN64 */
#define INTPTR_MIN     INT32_MIN
#define INTPTR_MAX     INT32_MAX
#define UINTPTR_MAX     UINT32_MAX
#endif /* _WIN64 */

If you have any further questions, feel free to E-mail me at stl@microsoft.com .
