✨ RAISE(3POSIX) ✨

okay bestie, welcome to the POSIX Programmer's Manual 💖 this one's RAISE(3POSIX), and yes the vibes are immaculate but the facts are staying exactly where they are, no cap.

🌸 PROLOG 🌸

so like, this manual page is part of the POSIX Programmer's Manual. heads up though: the Linux implementation of this interface may differ (so pls consult the corresponding Linux manual page for the deets on Linux behavior), or — plot twist — the interface may not even be implemented on Linux. 🙈

👑 NAME 👑

raise — send a signal to the executing process. that's it, that's the whole job. sending a signal. to itself. main character energy fr. 💅

🎀 SYNOPSIS 🎀

#include <signal.h>

int raise(int sig);

🦋 DESCRIPTION 🦋

okay so the functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional — nobody's trying to start drama. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt. ✨

The raise() function shall send the signal sig to the executing thread or process. and listen — if a signal handler is called, the raise() function shall not return until after the signal handler does. like it's not leaving the party before its friend does, iconic behavior honestly. 🫶

the effect of the raise() function shall be equivalent to calling:

pthread_kill(pthread_self(), sig);

💖 RETURN VALUE 💖

Upon successful completion, 0 shall be returned. slay. ✅

Otherwise, a non-zero value shall be returned and errno shall be set to indicate the error. not slay. 😭

💀 ERRORS 💀

the raise() function shall fail if:

  • EINVAL — The value of the sig argument is an invalid signal number. like bestie that is not a real signal, i cannot send that, absolutely not. 🚫

The following sections are informative.

🌈 EXAMPLES 🌈

None. (yes fr, there are genuinely none, we're all just vibing here 🧚)

🍓 APPLICATION USAGE 🍓

None. (same energy, nothing to add, we stay unbothered 💜)

⭐ RATIONALE ⭐

The term ``thread'' is an extension to the ISO C standard. iykyk. 👑

🦄 FUTURE DIRECTIONS 🦄

None. (the future is bright and also empty, we love a clean slate ✨)
