CK_RWCOHORT_INIT(3) BSD Library Functions Manual CK_RWCOHORT_INIT(3)NAMECK_RWCOHORT_INIT — initialize instance of a cohort-based reader-writer
lock type
LIBRARY
Concurrency Kit (libck, -lck)
SYNOPSIS
#include <ck_rwcohort.h>
CK_RWCOHORT_NEUTRAL_INIT(COHORT_NAME cohort_name, LOCK *lock);
CK_RWCOHORT_RP_INIT(COHORT_NAME cohort_name, LOCK *lock,
unsigned int wait_limit);
CK_RWCOHORT_WP_INIT(COHORT_NAME cohort_name, LOCK *lock,
unsigned int wait_limit);
DESCRIPTION
This macro initializes the lock instance pointed to by the 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
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 wait_limit argument, you
should use CK_RWCOHORT_STRATEGY_DEFAULT_LOCAL_WAIT_LIMIT.
