Which C/C++ header file defines a BYTE data type?

I'm porting a header with this declaration:

 struct tMaterialInfo {     
    char strName[255]; // the texture name
    char strFile [255]; // the texture
     BYTE color [3]; // the color of the object 
 };

The header has the following includes:

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <fstream>
#include <vector>
#include <gl\gl.h> // Header File For The OpenGL32 Library
#include<gl\glu.h>// Header File For The GLu32 Library
#include <gl\glaux.h>

Where does that BYTE come from?

If you are programming C for Windows I assume you are using Visual Studio to develop. You can right click on any keyword and select Go To Definition F12 to find where it is defined.

BYTE is defined in WinDef.h

typedef unsigned char       BYTE;

Almost certainly from one of the many headers included from windows.h. The Windows SDK has included typedefs for BYTE, WORD, and DWORD since at least Windows 2.0 days (the earliest Windows SDK I recall having).

I'm guessing it's from Windows.

A byte (8 bits).

This type is declared in WinDef.h as follows:

typedef unsigned char BYTE;
