I want to know the opengl extensions, using glGetStringi, but the code doesn't compile. What the include for glGetStringi?
I'm using Code::Blocks with mingw on windows 7.

My code:

#include <iostream>
#include "GL/gl.h"
#include <windows.h>

using namespace std;

int main()
{
int max = 0;
glGetIntegerv(GL_EXTENSIONS, &max);

for(int i = 0; i < max; i++)
cout << glGetStringi(GL_EXTENSIONS, i) << endl;


return 0;
}
