Reply solicitation calls

Reply solicitation calls retrieve the reply for an asynchronous call. A user application that issues asynchronous calls can have several ECI requests outstanding at any time. It is the responsibility of the calling application to solicit the reply for an ECI request. If no reply is available, reply solicitation calls can either wait for a reply or return control directly to the user application. There are two types of reply solicitation call:
General
Retrieves any reply for any outstanding ECI request.
Specific
Retrieves a reply for a specific ECI request. A unique message qualifier is used to identify the reply for that request. It is the responsibility of the programmer to assign different message qualifiers to different asynchronous calls within a single application.
