c++ - Non - blocking RPC invocation, using gSoap -

is possible?

i know, can make one-way asynchronous communication, want two-way.

in other words, i'm asking request/response pattern, non-blocking, described here (the 3^rd option)

_{related asynchronous, acknowledged, point-to-point connection using gsoap - i'd make (n)acks async,}

i think not possible basic usage, way make 2 way via response 'results of call'

but might want use little trick 1] create server2 @ client end , call server2 server or if thats not can on internet because of nat / firewall etc
2] re architect api client calls server again based on servers responce first time.
