CK_RWCOHORT_PROTOTYPE(3)

💖 CK_RWCOHORT_PROTOTYPE — the whole manual page, bestie edition 💖

okay so you're here because you wanna spin up a reader-writer cohort-based lock using a cohort type you picked yourself. and honestly? iconic choice. let's get into it 🫶

✨ NAME ✨

CK_RWCOHORT_PROTOTYPE — define a reader-writer cohort-based lock using the cohort type you specify. that's the whole vibe. 🌸

📚 LIBRARY 📚

Concurrency Kit — that's libck, and you link it with -lck. periodt. 💅

🌈 SYNOPSIS 🌈

#include <ck_rwcohort.h>

CK_RWCOHORT_NEUTRAL_PROTOTYPE(COHORT_NAME cohort_name);

CK_RWCOHORT_RP_PROTOTYPE(COHORT_NAME cohort_name);

CK_RWCOHORT_WP_PROTOTYPE(COHORT_NAME cohort_name);

🦋 DESCRIPTION 🦋

okay so here's the tea, bestie. the ck_rwcohort.h header file does NOT define any cohort types for you. like, zero. none. it's giving "you're on your own, babe" energy. 😭

instead, you — yes you, main character — have to use the CK_RWCOHORT_PROTOTYPE macro to define whatever types you actually want. it takes a single argument, and that argument is the type of the cohort lock that your reader-writer lock should use. ✨

⚠️ lowkey important: a cohort type has to already exist with that name before you do any of this. you get it by defining it with the CK_COHORT_PROTOTYPE(3) or CK_COHORT_TRYLOCK_PROTOTYPE(3) macros first. no skipping steps, bestie, the vibe check demands order 🙈

and once you've defined your lock type, declaring an instance of it looks like this:

CK_RWCOHORT_INSTANCE(cohort_name) lock;

slay. that's a lock. you did that. 👑
