[ofw] [PATCH] uDAPL v2: fix dtest to handle CNO events properly
Davis, Arlin R
arlin.r.davis at intel.com
Tue Aug 4 22:32:06 PDT 2009
modify dtest.c to cleanup CNO wait code and consolidate into
collect_event() call. After waking up from CNO wait the
consumer must check all EVD's. The EVD's under the CNO
could be dropped if already triggered or could come in any order.
DT_RetToString changed to DT_RetToStr and DT_EventToSTr
changed to DT_EventToStr for consistency.
