As an alternative to size_t and ptrdiff_t, Windows-developers can use types DWORD_PTR, SIZE_T, SSIZE_T etc. But still it is desirable to confine to size_t and ptrdiff_t types. Safety of ptrdiff_t and size_t types in address arithmetic ...

Basically all data types like int, unsigned int, long, unsigned long, short, unsigned short, DWORD etc. remain the same in 32-bit and 64-bit environments. Other data types like size_t, INT_PTR, LONG_PTR, DWORD_PTR, ULONG_PTR etc. and pointers like LPCTSTR will be 32-bit long ...
