1.3 equivalent of SDL_saveBMP

SDL Development
1

hello,
in 1.2 one could save the primary surface in a nice bitmap with
SDL_saveBMP; is there and which is it the equivalent function for 1.3
and SDL_Window?
i tried the common glReadPixels but that seemed to interfere with the
gl handling of sdl and caused many crashes

bye

Code:
/**

  • \brief Read pixels from the current rendering target.*
  • \param rect A pointer to the rectangle to read, or NULL for the entire
  •            render target.
  • \param format The desired format of the pixel data, or 0 to use the format
  •            of the rendering target
  • \param pixels A pointer to be filled in with the pixel data
  • \param pitch The pitch of the pixels parameter.
  • \return 0 on success, or -1 if pixel reading is not supported.
  • \warning This is a very slow operation, and should not be used frequently.
    */
    extern DECLSPEC int SDLCALL SDL_RenderReadPixels(const SDL_Rect * rect,
    Uint32 format,
    void *pixels, int pitch);

this is the equivalent of glReadPixels.
