Application Programming Interfaces
Example of an open channel call in an RTR client program:
Sample C client
code
status = rtr_open_channel(&Channel,
if (Status != RTR_STS_OK)
Example of a receive message call in an RTR server program:
Sample C server
code
status = rtr_receive_message(&Channel,
if (status != RTR_STS_OK)
A client can have one or multiple channels, and a server can
have one or multiple channels. A server can use concurrent
servers, each with one channel. How you create your design
depends on whether you have a single CPU or a multiple CPU
machine, and on your overall design goals and implementation
requirements.
