🌸 PROLOG 🌸

okay bestie, before we even get into it, real talk: this page is part of the POSIX Programmer's Manual. The Linux version of this interface might be different (so like, go check the matching Linux manual page for what Linux actually does), or honestly it might just not be implemented on Linux at all. 💀
