The ECI_GET_SPECIFIC_REPLY_WAIT call type provides a reply solicitation
call to return information appropriate to any outstanding reply that
matches the input
eci_message_qualifier. If there is
no such reply, the application waits until there is. (You can get an indication
that no reply is available by using call type ECI_GET_SPECIFIC_REPLY instead.)
Note: It is important that the Eci parameter blocks of outstanding ECI_STATE_ASYNC
calls are not modified before the results of the call are received. Results
will be incorrect if these blocks are modified before this stage.
