CK_COHORT_PROTOTYPE(3) DragonFly Library Functions Manual
NAME
CK_COHORT_PROTOTYPE - define cohort type with specified lock types
LIBRARY
Concurrency Kit (libck, -lck)
SYNOPSIS
#include <ck_cohort.h>
CK_COHORT_PROTOTYPE(COHORT_NAME cohort_name, TYPE global_lock_method,
LOCK_FXN global_unlock_method, LOCK_FXN local_lock_method,
LOCK_FXN local_unlock_method);
DESCRIPTION
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;
