BYTE, WORD and DWORD macros definition

Question

I am trying to understand, what would be the best way to define BYTE, WORD and DWORD macros, which are mentioned in answers of this qu

Answer 1

You have it defined at: https://msdn.microsoft.com/en-us/library/windows/desktop/aa383751(v=vs.85).aspx, and that is already defined in Windows Data Type headers for WinAPI:

typedef unsigned short WORD;
typedef unsigned char BYTE;
typedef unsigned long DWORD;

and it is a type, and not a macro.

Answer 2

This is a portable solution:

#include <stdint.h>

typedef uint32_t DWORD;   // DWORD = unsigned 32 bit value
typedef uint16_t WORD;    // WORD = unsigned 16 bit value
typedef uint8_t BYTE;     // BYTE = unsigned 8 bit value
