💅 PTHREAD_RWLOCK_DESTROY(3) — Library Functions Manual 💅

okay so bestie, welcome to the pthread_rwlock_destroy page ✨ this one lives in the Library Functions Manual, section 3, and it's lowkey the cleanup era of rwlock content 🎀

🌸 NAME 🌸

pthread_rwlock_destroy — destroy a read/write lock 🦋

like, the read/write lock gets its moment to exit the chat ✨

---

💖 LIBRARY 💖

POSIX Threads Library (libpthread, -lpthread) 🫶

yup, that's the one. link it and you're golden 💅

---

✨ SYNOPSIS ✨

#include <pthread.h>

int
pthread_rwlock_destroy(pthread_rwlock_t *lock);

that's the whole vibe. one lock pointer, one int coming back 😌

---

🎀 DESCRIPTION 🎀

The pthread_rwlock_destroy() function is used to destroy a read/write lock that was previously created with pthread_rwlock_init(). 🌈

that's it. that's the whole thing. you made it with init, you un-make it with destroy. it's giving closure 🧚

---

⭐ RETURN VALUES ⭐

If successful, pthread_rwlock_destroy() will return zero 😌✨ zero is the good number, the slay number, the "we ate and left no crumbs" number 💅

Otherwise an error number will be returned to indicate the error 😭 so if you get anything that isn't zero, that's a whole error number, not just a random int, bestie — read it accordingly 👑

---

💀 ERRORS 💀

not every destroy goes to plan, and here's the breakdown fr fr:

The pthread_rwlock_destroy() function will fail if:

• [EPERM] — The caller does not have the privilege to perform the operation 🙈 like, security said no. take the L gracefully.

The pthread_rwlock_destroy() function may fail if:

• [EBUSY] — The system has detected an attempt to destroy the object referenced by lock while it is locked 🔥 bestie do NOT do this, the lock is literally still in use, this is not the moment.
• [EINVAL] — The value specified by lock is invalid 💀 check your pointer, bestie, that thing is not doing what you think it's doing.
