💖 CK_RWCOHORT_READ_LOCK(3) 💖

okay so bestie, welcome to section 3 of the manual, courtesy of the Concurrency Kit — aka libck, aka the girlies who make locks that actually scale 🦋 this one's all about grabbing read-only permission from a cohort-based reader-writer lock. no cap.

✨ NAME ✨

🎀 SYNOPSIS 🎀

#include <ck_cohort.h>

CK_RWCOHORT_NEUTRAL_READ_LOCK(COHORT_NAME cohort_name, LOCK *lock,
    COHORT *cohort"void *global_context, void *local_context);

CK_RWCOHORT_RP_READ_LOCK(COHORT_NAME cohort_name, LOCK *lock,
    COHORT *cohort"void *global_context, void *local_context);

CK_RWCOHORT_WP_READ_LOCK(COHORT_NAME cohort_name, LOCK *lock,

bestie, notice that lil " in there? that's literally what's in the page. copying it exactly, not my job to fix it, my job is to be faithful 💅

🌸 DESCRIPTION 🌸

so this call acquires read-only permission from lock. 🫶 and it's not gonna just hand it over instantly — the call will block until that permission has actually been acquired. patient queen energy.

cohort must point to a cohort whose global lock is the same as all other cohorts used with lock. like, they all have to be in the same group chat, fr fr — mismatched global locks is not the vibe.

the global_context and local_context arguments get passed along as the context arguments to any calls to cohort. so they travel with you, iconic. ✨
