         COHORT *cohort"void *global_context, void *local_context);

     CK_RWCOHORT_RP_READ_LOCK(COHORT_NAME cohort_name, LOCK *lock,
         COHORT *cohort"void *global_context, void *local_context);

         COHORT *cohort"void *global_context, void *local_context);

DESCRIPTION

     This call will acquire read-only permission from lock.  The call will block until this
     permission has been acquired.  cohort must point to a cohort whose global lock is the same
     as all other cohorts used with lock.  The global_context and local_context arguments will be
     passed along as the context arguments to any calls to cohort.
