How to implement client-server (messaging) under qnx 4.25?

Question

QNX

Where can I find implementation information?
QNX 4.25
Task
Implement console applications: “client” and “server”. Communication between processes is carried out on the basis of interprocess communication “message passing”.
Types of transmitted data from “client” to “server”:
• number;
• line.
Types of transmitted data from “server” to “client”:
• string. The “Client”
logic transmits to the “server” information about the entered data.
The “server” displays the received data and sends a response to the “client” with an acknowledgment that the data has been received.
Requirements
Requirements for the “server” application:
• the name is specified in the command line parameter;
• displaying information about the client when receiving data;
• The display of the received data is carried out with the indication of the data type.
Requirements for the “client” application:
• the name of the “server” is specified in the command line parameter;
• data entry indicating the type of transmitted data;
• restoration of “connection” in case of connection loss.
