SIGWAITINFO(3POSIX)

💖 sigwaitinfo — the "bestie, just wait for your signals" page 💖

okay so real talk, this one comes straight out of the POSIX Programmer's Manual — that's the SIGWAITINFO(3POSIX) situation, if you're keeping track of the header, which I know you are bestie 💅

🚨 PROLOG (read this first, no skipping) 🚨

okay so before literally anything else: this manual page is part of the POSIX Programmer's Manual. the Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the details of Linux behavior, fr fr. and like… the interface might not even be implemented on Linux at all. imagine 💀

not me warning you about portability before you've even read the function name. but that's the vibe. 🫶
