🦋 sigpending(3P) — the POSIX Programmer's Manual, bestie edition 🦋

okay so this is a page from the POSIX Programmer's Manual, and the header situation is literally SIGPENDING(3P) — that's the title, that's the manual, we love her 💅

⚠️ PROLOG, and it's important, don't scroll past: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so go consult the corresponding Linux manual page for the deets on Linux behavior. Or… the interface may not be implemented on Linux at all. 🫠 So like, vibe check your platform first, okay?

okay so here's the tea: sigpending() shall 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.

it's giving "who's waiting at the door and why can't they get in" 🚪✨ literally blocked and pending at the same time. iconic.
