🌸 PROLOG 🌸

So like, real talk first, bestie: this manual page is part of the POSIX Programmer's Manual. That's the whole vibe of the document you're reading rn.

But heads up (and this is important, not just me being dramatic 😭):

• the Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the deets on Linux behavior, fr fr
• or… plot twist… the interface may not be implemented on Linux at all 💀

so don't come for me if your Linux box is like "who?" — check the Linux page first, periodt.
