NAME¶
CK_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.
