CK_COHORT_PROTOTYPE(3)

💅 CK_COHORT_PROTOTYPE — bestie's guide to defining a cohort type (3)

okay so like. you're in ck_cohort land. hi. welcome. 🫶

📚 LIBRARY

Concurrency Kit (libck, -lck) — yes girl, link it.

✨ SYNOPSIS ✨

#include <ck_cohort.h>

CK_COHORT_PROTOTYPE(COHORT_NAME cohort_name, TYPE global_lock_method,
    LOCK_FXN global_unlock_method, LOCK_FXN local_lock_method,
    LOCK_FXN local_unlock_method);

🌸 DESCRIPTION 🌸

here's the tea, bestie: ck_cohort.h ships with absolutely zero cohort types defined. not one. empty. the header is giving "i'm just a template, do it yourself" energy. 😭

so you — the main character — have to define whatever types you want using the CK_COHORT_PROTOTYPE or CK_COHORT_TRYLOCK_PROTOTYPE(3) macros. and heads up: if you want your cohort type to support trylock operations, you have to use CK_COHORT_TRYLOCK_PROTOTYPE. CK_COHORT_PROTOTYPE is not the one for that, no cap. 💀

the CK_COHORT_PROTOTYPE macro eats the following arguments:

• cohort_name — an identifier for this cohort type. this is the name you'll be passing to literally every other CK_COHORT macro, so remember it. it's the moment, it's the brand, it's the whole identity. 👑
• global_lock_method — the method that should be called to acquire the global lock 🔥
• global_unlock_method — the method that should be called to relinquish the global lock
• local_lock_method — the method that should be called to acquire the local lock ✨
• local_unlock_method — the method that should be called to relinquish the local lock

and once you've defined your lil type? you declare instances of it like this:

CK_COHORT_INSTANCE(cohort_name) cohort;

look at you. iconic. defining types. slaying. 🎀
