🦋 PROLOG 🦋

okay bestie, quick heads up before we dive in 💖 This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so like, go check the corresponding Linux manual page for the deets on Linux behavior — or honestly the interface might not even be implemented on Linux at all. 🙈

✨ NAME ✨

sigfillset — initialize and fill a signal set

So this is the sigfillset(3P) page, from the POSIX Programmer's Manual. She's iconic, she's tiny, she fills signal sets. Periodt.

🌸 SYNOPSIS 🌸

#include <signal.h>

int sigfillset(sigset_t *set);

💅 DESCRIPTION 💅

The sigfillset() function shall initialize the signal set pointed to by set, such that all signals defined in this volume of POSIX.1‐2017 are included.

that's it. that's the whole job. she fills the set. all of it. every signal POSIX.1‐2017 knows about, in one set. slay 💖

👑 RETURN VALUE 👑

Upon successful completion, sigfillset() shall return 0. 🎀

Otherwise, it shall return -1 and set errno to indicate the error. 😭

💀 ERRORS 💀

like, genuinely, just go read that one. she explains the whole vibe. 🫶
