CK_RWCOHORT_INSTANCE(3)                     DragonFly Library Functions Manual

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)));
