glBindTexture(GL_TEXTURE_2D, texture). if you select the texture with this then glCopyTexSubImage2D will copy the framebuffer to the texture.

As your leader, I encourage you from time to time, and always in a respectful manner, to question my logic. If you're unconvinced that a particular plan of action I've decided is the wisest, tell me so, but allow me to convince you and I promise you right here and now, no subject will ever be taboo. Except, of course, the subject that was just under discussion. The price you pay for bringing up either my Chinese or American heritage as a negative is - I collect your f***ing head.

goto www.opengl.org and see the faq Q/ how to draw a fullscreen quad or something
alternately u can get the textures data with glGetTexImage..(..) or someit
