How to stretch an SDL window to fullscreen?

Question

I am interested in using SDL for graphics. I didn't use it before because when I went into fullscreen mode I would get black borders on the left and right side. I switched to SFML, and it worked just fine because I wasn't in fullscreen mode, but I had a window that stretched to the entire screen. The graphics stretched along with it. I've been noticing a few games are beginning to use a windowed-fullscreen mode.

Is there a way to stretch SDL's window with graphics instead of pure fullscreen mode?

Assuming that the black bars are there at all because the resolution you chose didn't match the screen (in which case, try to use a resolution that fits perfectly), I think this is a per-PC graphics card setting type o'thingy and not something you'd expect to change from your program. — Leushenko
@Leushenko: Yes, although the goal is to just stretch a borderless window with its graphics to a full screen. I understand that SDL doesn't stretch when going into fullscreen mode. — Phil

Consider using this function to get fullscreen:

SDL_SetWindowFullscreen - https://wiki.libsdl.org/CategoryVideo

And just this function to stretch it to the screen size:

SDL_MaximizeWindow - https://wiki.libsdl.org/SDL_MaximizeWindow

Hope that was what you were looking for.
