do_sigtimedwait(9)

✨ do_sigtimedwait — Kernel API Manual ✨

okay bestie, gather round, because we're talking about do_sigtimedwait(9), a kernel API manual page, and honestly? it's giving "short but mighty" 💅

---

🌸 NAME 🌸

do_sigtimedwait — wait for queued signals specified in @which 🎀

like, literally just sit there and wait for the signals you asked for. no cap.

---

🦋 SYNOPSIS 🦋

int do_sigtimedwait (const sigset_t *which , kernel_siginfo_t *info ,
       const struct timespec64 *ts );

this is the whole signature, character for character, don't come for me 🙈

---

💖 ARGUMENTS 💖

• which — the queued signals you're waiting for. this is your wishlist, bestie 🫶
• info — if it's non-null, the signal's siginfo gets returned right here. the tea gets delivered directly to this address ✨
• ts — upper bound on process time suspension. aka the "how long am I willing to wait for this" clock ⏰

lowkey obsessed with how short this page is. short page, big signal energy 💀

sign-off era 🧚‍♀️💜

so this little gem lives in the source/version ./kernel, dated October 2026, and that's the whole page bestie — slay, periodt, go read some signals 🍓✨
