✨ cSignal ✨

okay so bestie, we're talking about cSignal(3) from the util/ulocks.h squad 💅 she lives in the ClearSilver world and she has ONE job, and she does it flawlessly, no cap.

🎀 NAME 🎀

cSignal — send signal to one waiting thread. that's it. that's the whole gig. one thread. not two. not all of them. ONE. 👑

🌸 SYNOPSIS 🌸

#include <util/ulocks.h>

NEOERR *cSignal(pthread_cond_t *cond);

look at her. so small. so powerful. 🦋

💖 ARGUMENTS 💖

• cond — the condition variable you're sending the signal on. that's the target, bestie, that's who's getting poked. 📣

✨ DESCRIPTION ✨

Sends a signal to one thread waiting on condition variable cond. literally just one. if there's a whole crowd of threads camped out on that condition variable, only one of them gets the ✨vibe check✨ and wakes up. the rest are still napping, iykyk. 😴

MT-Level: Safe. 🛡️ so you can call her from multiple threads and she will not betray you. she's built different fr fr.

🫶 RETURN VALUE 🫶

None. nothing. zero. nada. she returns void of vibes, she just does the thing and leaves. main character energy honestly. 💅
