57 * We compile SDL into a DLL. This means, that it's the DLL which
58 * creates a new thread for the calling process with the SDL_CreateThread()
59 * API. There is a problem with this, that only the RTL of the SDL.DLL will
60 * be initialized for those threads, and not the RTL of the calling
61 * application!
62 *
63 * To solve this, we make a little hack here.
64 *
65 * We'll always use the caller's _beginthread() and _endthread() APIs to
66 * start a new thread. This way, if it's the SDL.DLL which uses this API,
67 * then the RTL of SDL.DLL will be used to create the new thread, and if it's
68 * the application, then the RTL of the application will be used.
69 *
70 * So, in short:
71 * Always use the _beginthread() and _endthread() of the calling runtime
72 * library!
