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.
