PTHREAD..._TRYLOCK(3POSIX)

💖 PTHREAD..._TRYLOCK(3POSIX) 💖

okay bestie, welcome to the POSIX Programmer's Manual ✨ this page lives in that family, and it's here to tell you about pthread_mutex_trylock and pthread_mutex_unlock — the two chaotic siblings of pthread_mutex_lock.

🌸 PROLOG 🌸

so like, real talk first 🫶 — this manual page is part of the POSIX Programmer's Manual. the Linux implementation of this interface may differ (bestie, go check the corresponding Linux manual page for the details on Linux behavior), or the interface may not be implemented on Linux at all. no cap. 💀

🎀 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 🦋

ngl, there's not much here — it literally just says: refer to pthread_mutex_lock(). that's it. that's the whole vibe. go read that one, bestie, iykyk 👑
