💖 sigfillset — the POSIX Programmer's Manual, bestie edition 💖

okay so real quick before we even start: this page is part of the POSIX Programmer's Manual, and it's filed under SIGFILLSET(3POSIX). 🎀

🌸 PROLOG 🌸

okay so this manual page is part of the POSIX Programmer's Manual, periodt. the Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for details on Linux behavior 💅. orrr the interface might not even be implemented on Linux at all. lowkey tragic, but we move. 🦋

✨ NAME ✨

sigfillset — initialize and fill a signal set 🌈

👑 SYNOPSIS 👑

#include <signal.h>

int sigfillset(sigset_t *set);

💫 DESCRIPTION 💫

so 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. literally all of them. the whole roster. the full squad. no one left out, no cap. 🫶

🔥 RETURN VALUE 🔥

upon successful completion, sigfillset() shall return 0. slay. 💖

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

💀 ERRORS 💀

no errors are defined. not a single one. iconic behavior honestly. ✨

the following sections are informative. (yes, that's a real thing the standard says, i'm not making it up 🧚)

🍓 EXAMPLES 🍓

none. bestie, there is literally nothing here. 🙈

🔮 FUTURE DIRECTIONS 🔮

none. the future is a mystery, but it's not this. 💅
