C++ (Cpp) SDL_EGL_UnloadLibrary Examples

Example #1

File: SDL_windowsopengles.c Project: ianmaclarty/amulet

int
WIN_GLES_SetupWindow(_THIS, SDL_Window * window)
{
    /* The current context is lost in here; save it and reset it. */

        return SDL_SetError("Could not create GLES window surface");
    }

Example #2

File: SDL_egl.c Project: Gotusso/Urho3D

void
SDL_EGL_DeleteContext(_THIS, SDL_GLContext context)
{
    EGLContext egl_context = (EGLContext) context;

    /* Clean up GLES and EGL */

        SDL_EGL_MakeCurrent(_this, NULL, NULL);
        _this->egl_data->eglDestroyContext(_this->egl_data->egl_display, egl_context);
    }

    /* FIXME: This "crappy fix" comes from the X11 code,
     * it's required so you can create a GLX context, destroy it and create a EGL one */
    SDL_EGL_UnloadLibrary(_this);
}

Example #3

File: SDL_miropengl.c Project: Derek-OBrien/DsdlEngine

void
MIR_GL_UnloadLibrary(_THIS)
{

}
