🦋 DESCRIPTION 🦋

The sem facility provides system calls used by the standard C library (libc) to implement POSIX semaphores ✨

This facility offers support for such functions as sem_init() and sem_wait() 💖

It is available both as a kernel option for static inclusion and as a dynamic kernel module — so you've got options, bestie, and both of them slay 🎀
