Is C++ SDL and (Python PyGame) used by people other than hobbyists?

As a hobbyists who has a little experience making 2D games using PyGame, and has ventured into using C++ with the SDL library (in Visual开发者_开发百科 Studio), I'm curious. Is the library used professionally?

Doom3 and Unreal Tournament are on that list, so I'd say it is used professionally

SDL is used professionally and some great games were made with it. Many times it is used as a cross-platform window creation system to initialize openGL (as I assume it is used for Doom3, UT, etc...). It is also used for as "raw" 2d graphics API (for example in Battle For Wesnoth).
