What is the compatible API of a glDrawBuffer in OGLES2?

Hi,

I am new to OpenGLES2.0 and I want to draw something on back buffer. Could you please let me know how I can do it in OGLES2.0.

Thanks.

By default egl window surfaces are double buffered, if you issue gl draw calls and do an eglSwapBuffers(), the contents will be rendered to your windows back buffer. However, rendering may not be complete when the eglSwapBuffers(), returns. If you want to force rendering to complete, you need to call glFinish().

Thanks a lot!
