SELECT(3POSIX)

💅 SELECT(3POSIX) — the POSIX Programmer's Manual era ✨

okay bestie, quick vibe check before we even start: this page lives in the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux at all. So like… check your local manpage before you come for me 🫶

🌸 PROLOG 🌸

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

fr fr, read that twice. POSIX said what it said, Linux might be doing its own little thing, and your kernel might be like "never heard of her" 💀

✨ NAME ✨

select — synchronous I/O multiplexing 👑

🎀 SYNOPSIS 🎀

#include <sys/select.h>

int select(int nfds, fd_set *restrict readfds,
    fd_set *restrict writefds, fd_set *restrict errorfds,

look at that signature. so clean. so restrict. so much power in five arguments 💖

🦋 DESCRIPTION 🦋

Refer to pselect().

that's it. that's the whole description. iconic behaviour honestly — this page is giving "go ask my sister, she explains it better" 😭
