I could not even find a mention what platform it supports. There is a Linux example on the bottom. Have never seem a libc implementation that does not even mention for which platforms it is meant.

> sp.h is written in C99, and it compiles against any compiler and libc imaginable. It works on Linux, on Windows, on macOS. It works under a WASM host. It works in the browser. It works with MSVC, and MinGW, it works with or without libc, or with weird ones like Cosmopolitan. It works with the big compilers and it works with TCC.

You could, of course, spend 30 seconds look at the code on Github which you would have to do if you were interested in using it anyway?
