- Always use internal qsort and bsearch implementation. - add "_r" reentrant versions. The reasons for always using the internal versions is that the C runtime versions' callbacks are not mark STDCALL, so we would have add bridge functions for them anyhow, The C runtime qsort_r/qsort_s have different orders of arguments on different platforms, and most importantly: qsort() isn't a stable sort, and isn't guaranteed to give the same ordering for two objects marked as equal by the callback...as such, Visual Studio and glibc can give different sort results for the same data set...in this sense, having one piece of code shared on all platforms makes sense here, for reliabillity. bsearch does not have a standard _r version at all, and suffers from the same SDLCALL concern. Since the code is simple and we would have to work around the C runtime, it's easier to just go with the built-in function and remove all the CMake C runtime tests. Fixes #9159.
Simple DirectMedia Layer (SDL) Version 3.0
Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting with README.md. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.
Enjoy!
