After this macro has been called, the cohort +pointed to by the +.Fa cohort +argument will use the lock pointed to by +.Fa global_lock +as its global lock and the lock pointed to by +.Fa local_lock +as its local lock. +.Pp +The cohort will relinquish its global lock after +.Fa pass_limit +consecutive acquisitions of its local lock, even if there are other threads waiting. +If you are unsure of a value to use for the +.Fa pass_limit +argument, you should use CK_COHORT_DEFAULT_LOCAL_PASS_LIMIT. +.Sh SEE ALSO +.Xr ck_cohort 3 , +.Xr CK_COHORT_PROTOTYPE 3 , +.Xr CK_COHORT_TRYLOCK_PROTOTYPE 3 , +.Xr CK_COHORT_INSTANCE 3 , +.Xr CK_COHORT_INITIALIZER 3 , +.Xr CK_COHORT_LOCK 3 , +.Xr CK_COHORT_UNLOCK 3 , +.Xr CK_COHORT_LOCKED 3 , +.Xr CK_COHORT_TRYLOCK 3 , +.Pp +Additional information available at http://concurrencykit.org/ |
