To know about all the supported functions in OpenGL ES, you must have to download the OpenGL ES 1.0 manual and its specification from this site.

Direct access to the framebuffer is pretty slow on HW accelerated implementations hence support was removed from OGLES. You'll have to translate your accesses into polygons.

Another option is to write your pixel updates into your own allocated memory array and then create a texture from this memory area and then update the framebuffer area by rendering a quad textured with your generated texture.

Hope this helps,
