📦 version 2017a, in debian bookworm, debian trixie, ubuntu jammy, ubuntu noble, ubuntu resolute, ubuntu stonking

✨ PROLOG ✨

ok bestie before we even start, real talk: this 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 🎀

sigpending — examine pending signals

🦋 SYNOPSIS 🦋

#include <signal.h>

int sigpending(sigset_t *set);

💖 DESCRIPTION 💖

So the sigpending() function is gonna store, in the location referenced by the set argument, the set of signals that are blocked from delivery to the calling thread and that are pending on the process or the calling thread. Like it's giving you the receipts on which signals are stuck waiting in line. 👑

🌸 RETURN VALUE 🌸

Upon successful completion, sigpending() shall return 0. Otherwise, -1 shall be returned and errno set to indicate the error. Slay if it works, sad girl hours if it doesn't. 😭

💅 ERRORS 💅

No errors are defined. Not a single one. Iconic, honestly.

The following sections are informative.

⭐ EXAMPLES ⭐

None. Nada. Nothing to see here. 🙈

🌈 APPLICATION USAGE 🌈

None. ✨

🧚 RATIONALE 🧚

None. 🫶

💜 FUTURE DIRECTIONS 💜

None. The future is unknowable and also empty. 🔮
