Hi,
in my multiplatform OpenGL application, i require WGL_EXT_swap_control extension capability.
I have it running properly on Linux and MacOSX.

In WinXP and Win7, glGetString(GL_EXTENSIONS) returns null (i still dont kwno why), so,
- how to know if WGL_EXT_swap_control extension is present?
- how to enable it?

regards
dani
