Instead, the user must use the CK_COHORT_PROTOTYPE or .Xr CK_COHORT_TRYLOCK_PROTOTYPE 3 macros to define any types they want to use. They must use CK_COHORT_TRYLOCK_PROTOTYPE if they want their cohort type to support trylock operations. The CK_COHORT_PROTOTYPE macro takes the following arguments: .Pp .Fa cohort_name : An identifier used for this cohort type. This will have to be passed to each of the other CK_COHORT macros. .br .Fa global_lock_method : The method that should be called to acquire the global lock .br .Fa global_unlock_method : The method that should be called to relinquish the global lock .br .Fa local_lock_method : The method that should be called to acquire the local lock .br .Fa local_unlock_method : The method that should be called to relinquish the local lock .Pp Instances of the defined cohort type can be declared as: .br CK_COHORT_INSTANCE(cohort_name) cohort; .Sh SEE ALSO .Xr ck_cohort 3 , .Xr CK_COHORT_TRYLOCK_PROTOTYPE 3 , .Xr CK_COHORT_INSTANCE 3 , .Xr CK_COHORT_INITIALIZER 3 , .Xr CK_COHORT_INIT 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/
