CK_RWCOHORT_INSTANCE — declare an instance of a cohort-based reader-writer lock type
Concurrency Kit (libck, -lck)
#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);
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)));
