PTHREAD_R...TRYRDLOCK(3P)

🌸 PROLOG 🌸

Okay bestie, real talk before we even get into it — this page is part of the POSIX Programmer's Manual. That matters, because the Linux implementation of this interface may differ (so if you're on Linux, go peek at the corresponding Linux manual page for the actual tea ☕), or honestly the interface might not even be implemented on Linux at all. Vibe check accordingly. 💀

✨ NAME ✨

pthread_rwlock_tryrdlock — lock a read-write lock object for reading 🎀

💅 SYNOPSIS 💅

#include <pthread.h>

int pthread_rwlock_tryrdlock(pthread_rwlock_t *rwlock);

That's the whole thing. Two lines. Iconic behavior, minimal packaging. ✨

🎀 DESCRIPTION 🎀

Not me about to explain this from scratch when the girlies already did it — literally just refer to pthread_rwlock_rdlock(). That's where the actual explanation lives. Go read that one, bestie, I promise it's worth it. 🫶
