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;
