SYNOPSIS
     #include <ck_cohort.h>

     CK_RWCOHORT_NEUTRAL_READ_LOCK(COHORT_NAME cohort_name, LOCK *lock,
	 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);

     CK_RWCOHORT_WP_READ_LOCK(COHORT_NAME cohort_name, LOCK *lock,
	 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 con-
     text arguments to any calls to cohort.
