usdf_cm_dgram_shutdown #9

Closed rfaucett closed 9 years ago

figure out what to do with dgram shutdown

xuywang commented 9 years ago

Rough idea below.

Check if ep is connected (eq->ep_dest != NULL). If not return FI_EPNOTCONNECT 

If (flags & FI_WRITE)
   ep->ep_fid.msg.send = usdf_dgram_send_shutdown (returns error when called)
                             sendv
if (flags & FI_READ)
   ep->ep_fid.msg.recv = usdf_dgram_recv_shutdown (returns error when called)
                             recv

Don't think it's necessary to send msg to remote peer to notify shutdown event.

we can't overwrite the fn calls like that because they live in a shared structure

shutdown now no longer applies to dgram
