NAME

CK_RWCOHORT_INSTANCE — declare an instance of a cohort-based reader-writer lock type

LIBRARY

Concurrency Kit (libck, -lck)

SYNOPSIS

#include <ck_cohort.h>

CK_RWCOHORT_NEUTRAL_INSTANCE(COHORT_NAME cohort_name);

CK_RWCOHORT_RP_INSTANCE(COHORT_NAME cohort_name);

CK_RWCOHORT_WP_INSTANCE(COHORT_NAME cohort_name);

DESCRIPTION

The user must use this macro to declare instances of lock types that they have defined using the CK_RWCOHORT_PROTOTYPE(3) macro. The cohort_name must be the same as the one used in the prototype macro. For instance, if CK_RWCOHORT_PROTOTYPE was called with the name "foo", the CK_RWCOHORT_INSTANCE macro should be called as
CK_RWCOHORT_INSTANCE(foo) cohort;

This macro should also be used when allocating memory for cohorts. For instance, to allocate a block of 4 cohorts:
CK_RWCOHORT_WP_INSTANCE(foo) *cohorts = malloc(4 * sizeof(CK_RWCOHORT_WP_INSTANCE(foo)));
