Is it possible to use sync objects in openGL 2.1?

OpengGL sync objects was introduced in openGL 3.2。I want to know if I create a openGL 2.1 context can I use sync ojbects if my driver support GL_ARB_sync extension?

I create a openGL 2.1 context can I use sync ojbects if my driver support GL_ARB_sync extension?

You can use any extension that your driver exposes support for. So if you create a 2.1 context, and you see GL_ARB_sync in the extension string, then you can use it.

thanks!
