Thank you for your interest.

Right now, the library can be used on both Linux and Windows (using MSYS2 or WSL which is my development environment). I have no access to a MacOS system, so I have not tested it there.

Except native operations such as files, networking and threads, everything else is written in C99, with portability in mind.

The library was highly inspired by the Java standard API. Yes, I have gone through SDL especially with threads and mutexes (which will be available in version 1.2).

Also, it would be great if you could list out any particular features you require.
