pthread_condattr_init(3)

✨ pthread_condattr_init(3) ✨

okay bestie, this one lives in the Library Functions Manual section 3 (that's the C library girlies, not the syscall girlies, iykyk) 💅

---

🎀 NAME 🎀

pthread_condattr_init, pthread_condattr_destroy — condition creation attributes ✨

---

🌸 SYNOPSIS 🌸

#include <pthread.h>

int pthread_condattr_init(pthread_condattr_t *attr);
int pthread_condattr_destroy(pthread_condattr_t *attr);

like, that's it. two functions. short and sweet, we love a minimal era 🫶

---

🦋 DESCRIPTION 🦋

so here's the vibe: condition attributes get specified at condition creation time, by passing a condition attribute object as the second argument to pthread_cond_init(3). 🧚

and if you pass NULL instead? that's lowkey equivalent to passing a condition attribute object with literally all the attributes chillin' at their default values. same energy, no cap. 💖

now for the tea, bestie: the LinuxThreads implementation supports no attributes for conditions. none. zero. the functions on condition attributes are only included for compliance with the POSIX standard. so they're basically there to look pretty in the group chat. 💀

pthread_condattr_init() initializes the condition attribute object attr and fills it up with the default values for the attributes. ✨

pthread_condattr_destroy() destroys a condition attribute object — and heads up, it must not be reused until it gets reinitialized. no zombie attribute objects, periodt. 🙈

and the plot twist? in the LinuxThreads implementation, both functions do nothing. iconic behavior honestly. they just show up, say hi, return, exit. 👑

---

⭐ RETURN VALUE ⭐

pthread_condattr_init() and pthread_condattr_destroy() always return 0. every single time. no drama, no surprises, no error codes jumping out at you. slay. 💅
