PTHREAD_MUTEX_TRYLOCK(3P)

💖 PTHREAD_MUTEX_TRYLOCK(3P) — the POSIX Programmer's Manual era 💖

okay bestie, so this page lives in the POSIX Programmer's Manual (yes, the 3P section, that's the whole vibe), and it's the one about trying to grab a mutex and giving up gracefully if it's not free. 🎀

✨ PROLOG ✨

okay so real talk first, this is the part nobody reads and everybody needs:

• This manual page is part of the POSIX Programmer's Manual.
• The Linux implementation of this interface may differ — so if you're on Linux, go check the corresponding Linux manual page for the actual Linux behavior, fr fr.
• Or… the interface may not be implemented on Linux at all. 💀 Like, it might just not exist there. Check before you ship, bestie.

🌸 NAME 🌸

pthread_mutex_trylock, pthread_mutex_unlock — lock and unlock a mutex

🦋 SYNOPSIS 🦋

#include <pthread.h>

int pthread_mutex_trylock(pthread_mutex_t *mutex);
int pthread_mutex_unlock(pthread_mutex_t *mutex);

💅 DESCRIPTION 💅

Refer to pthread_mutex_lock().

(That's it. That's the whole description. The POSIX girlies said "the lore is elsewhere" and honestly? Respect. 🙈 Go read pthread_mutex_lock() for the actual details — this page is just here to hand you the trylock-and-unlock receipts.)
