qthread_queue_join(3)

💖 qthread_queue_join — the "bestie, hold my spot" of libqthread 💖

okay so real quick, this is qthread_queue_join(3) from libqthread, and it's genuinely one of the cutest little calls in the whole library, no cap. Let's get into it. 🫶

✨ NAME ✨

qthread_queue_join — enter a queue and block until the queue is released

🌸 SYNOPSIS 🌸

#include <qthread.h>

int
qthread_queue_join (qthread_queue_t q);

🦋 DESCRIPTION 🦋

okay so what this does: the task that calls it gives up the processor and gets queued up in the queue you specified, just waiting there to be released later. like, it steps out of the lineup and goes and sits in the waiting room. 🪑

it's giving very much qthread_yield() energy — same vibe of "okay i'm done for now, someone else go" — but with a lil twist: another task has to release the queue before this task gets to run again. so it's not just "i'll be back whenever," it's "i'll be back when someone lets me back." main character waiting on a callback, honestly. 💅

🎀 RETURN VALUES 🎀

• QTHREAD_SUCCESS — slay, it worked. ✅
• QTHREAD_BADARGS — returned when q is invalid. so like, if you handed it a bogus queue, this is the "girl what" response. 🙈
