wglext - extension not installed in OpenGL context

Question

I am trying to disable vsync in OpenGl with WGL_EXT_swap_control using wglSwapIntervalEXT(int interval).

I am trying to include the wglext header but after much searchin

Answer 1

So, a friend managed to figure this out without glew. So if anyone needs help with it this should be something similar to what you are looking for

void SetVSync(bool sync)  
{   
typedef BOOL(APIENTRY *PFNWGLSWAPINTERVALPROC)(int);
PFNWGLSWAPINTERVALPROC wglSwapIntervalEXT = 0;

const char *extensions = (char*)glGetString(GL_EXTENSIONS);

wglSwapIntervalEXT = (PFNWGLSWAPINTERVALPROC)wglGetProcAddress("wglSwapIntervalEXT");

if (wglSwapIntervalEXT)
    wglSwapIntervalEXT(sync);
}
