The ck_cohort.h header file does not define any cohort types. Instead, the user must use the CK_COHORT_PROTOTYPE or 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:
cohort_name : An identifier used for this
cohort type. This will have to be passed to each of the other CK_COHORT
macros.
global_lock_method : The method that should be called to
acquire the global lock
global_unlock_method : The method that should be called
to relinquish the global lock
local_lock_method : The method that should be called to
acquire the local lock
local_unlock_method : The method that should be called
to relinquish the local lock
Instances of the defined cohort type can be declared as:
CK_COHORT_INSTANCE(cohort_name) cohort;
ck_cohort(3), CK_COHORT_TRYLOCK_PROTOTYPE(3), CK_COHORT_INSTANCE(3), CK_COHORT_INITIALIZER(3), CK_COHORT_INIT(3), CK_COHORT_LOCK(3), CK_COHORT_UNLOCK(3), CK_COHORT_LOCKED(3), CK_COHORT_TRYLOCK(3),
