In SDL 1.2, colorkey was a field in SDL_PixelFormat and could easily be read. It’s since been moved to the info struct inside the blitmap struct inside the SDL_Surface, and no SDL_GetColorKey API function was added. Could we get one please?
Yes, please 
I have been beating my head trying to figure out how to get
the colorkey.

As a workaround, you can get it like this:
BlitMap.info.colorkey
(You may need to replace some or all of the dots with arrows.)
Problem is, the BlitMap field is supposed to be “private,” according to the header, so that’s a less than ideal solution.________________________________

Hiyya, doing something like this?

My answer is use old sdl or use openGL…or wait-----------------

Sure!
/*

-
- \brief Sets the color key (transparent pixel) in a blittable surface.*
- \param surface The surface to update
- \param key A pointer filled in with the transparent pixel in the native surfa
ce format - \return 0 on success, or -1 if the surface is not valid or colorkey is not en
abled.
*/
extern DECLSPEC int SDLCALL SDL_GetColorKey(SDL_Surface * surface,
Uint32 * key);

Does this handle getting or just setting? The name combined with the
/brief confuses me.

Looks like it was carelessly cut-pasted from the SDL_SetColorKey info. The code looks right to me, though I’d prefer if the two different error conditions returned different error values.>----- Original Message ----
