Why does OpenGL don't need something like EGL in OpenGL ES

Hello,
does anybody of you know why OpenGL don’t need something like EGL in OpenGL ES?
Or is there something like EGL in OpenGL included?
Thank you

With GL, it depends on which platform you are on.

  1. On Windows, you use wgl

  2. On *nix systems, glX is used.

  3. On Mac’s, it use to be agl functions but I think they dumped these in favor of NSGL functions. I’m not sure. I’m not a Mac expert.

All that stuff has existed since the beginning, 1992.
When OpenGL ES was designed, they wanted to create a single interface for all PDA and cellphones and onboard PCs = EGL.
