.Dt CK_RWCOHORT_INIT 3
.Sh NAME
.Nm CK_RWCOHORT_INIT
.Nd initialize instance of a cohort-based reader-writer lock type
.Sh LIBRARY
Concurrency Kit (libck, \-lck)
.Sh SYNOPSIS
.In ck_rwcohort.h
.Fn CK_RWCOHORT_NEUTRAL_INIT "COHORT_NAME cohort_name" "LOCK *lock"
.Fn CK_RWCOHORT_RP_INIT "COHORT_NAME cohort_name" "LOCK *lock" "unsigned int wait_limit"
.Fn CK_RWCOHORT_WP_INIT "COHORT_NAME cohort_name" "LOCK *lock" "unsigned int wait_limit"
.Sh DESCRIPTION
This macro initializes the lock instance pointed to by the
.Fa lock
argument. Until a lock instance is initialized using the CK_RWCOHORT_INIT macro, any operations
involving it will have undefined behavior. Note that the
.Fa wait_limit
argument should only be used with reader-preference or writer-preference locks. For neutral
locks, this argument should be excluded.
If you are unsure of a value to use for the
.Fa wait_limit
argument, you should use CK_RWCOHORT_STRATEGY_DEFAULT_LOCAL_WAIT_LIMIT.
