How to show error messages with SDL...

How can I open windows to show errors while using SDL? I know that with GDI you can simply call MessageBox(), I want something similar with SDL.

You could always use the Windows API MessageBox() function directly (through windows.h), if you don't care about platform independency. For example:

Code:

#include <windows.h>
#include <SDL.h>

int main(int argc, char* argv[])
{
    if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_TIMER | SDL_INIT_AUDIO) != 0)
    {
        MessageBox(NULL, "Could not initialize SDL.", "Error", MB_OK | MB_ICONERROR);
        return 1;
    }

    // code

}

A portable way would be to use SDL in conjunction with wxWidgets, although I am not certain exactly how you would do that (haven't tried it myself).
