CK_COHORT_PROTOTYPE(3) Library Functions Manual CK_COHORT_PROTOTYPE(3)

NAME

CK_COHORT_PROTOTYPEdefine 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;
