Instead, the user must use +the CK_COHORT_PROTOTYPE or CK_COHORT_TRYLOCK_PROTOTYPE macros to define any types +they want to use. They must use CK_COHORT_TRYLOCK_PROTOTYPE if they want their cohort type to have support +for trylock operations. The CK_COHORT_TRYLOCK_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 global_locked_method +: This method should return true iff the global lock is acquired by a thread. +.br +.Fa global_trylock_method +: The method that should be called to try to acquire the global lock. +It should not block and return true iff the lock was successfully acquired. +.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 +.br +.Fa global_locked_method +: This method should return true iff the global lock is acquired by a thread. +.br +.Fa local_trylock_method +: The method that should be called to try to acquire the local lock. +It should not block and return true iff the lock was successfully acquired. +.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_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/ |
