The client
QNX SDP8.0Getting Started with the QNX OSDeveloperUser
The client wants to send a request to a server, block until the
server has completed the request, and then when the request is completed
and the client is unblocked, to get at the answer.
This implies two things: the client needs to be able to establish a connection
to the server and then to transfer data via messages—a message from the client to the
server (the send
message) and a message back from the
server to the client (the reply
message, the server's reply).
