sys_rt_sigpending(9)

💅 sys_rt_sigpending(9) — Kernel API Manual, but make it make sense ✨

okay so bestie, picture this: you're a signal, you got raised while you were blocked, and now you're just sitting there. pending. waiting. not me being ignored 😭. this page is literally the syscall that goes "hey, who's waiting in the queue rn?" and hands you back the list. no cap, that's the whole vibe. 🎀

---

✨ NAME ✨

sys_rt_sigpending — examine a pending signal that has been raised while blocked 💖

like, the signal showed up, it's there, but it's blocked so nothing's happened yet, and this syscall is the little peek behind the curtain. iconic behaviour honestly. 🦋

---

🌸 SYNOPSIS 🌸

long sys_rt_sigpending (sigset_t __user * uset , size_t sigsetsize );

lowkey a two-argument situation, we love a simple signature. 🫶

---

🎀 ARGUMENTS 🎀

• uset — stores pending signals 💅 this is where the answer lands, bestie. the pending set goes in here.
• sigsetsize — size of sigset_t type or larger 📏 that's it, that's the whole thing. it wants the size of the sigset_t type, or bigger. not smaller. don't try it. 🙈

ngl the signal rabbit hole is deep, but you've got this bestie. main character energy only. 👑
