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)));
