The SDL_CreateRenderer documentation mentions that the flags parameter can be either
Quote:
0, or one or more SDL_RendererFlags OR'd together
.

But what is the value of zero in this case? What does it default to?

Just took a look a the code, it basically says "give me a renderer with at-least these flags".  If you have no flags set, it gives you the best available renderer.  This list is something like:

Direct3d, Opengl, GLES2, GLES, DirectFB, PSP, and Software in that order.

I added a note on the wiki, if anyone feels the wording is misleading feel free to change it:

I added: Note that providing no flags gives priority to available SDL_RENDERER_ACCELERATED renderers.

Great, thanks a lot for clarifying that.
