Application Programming Interfaces
Sample C client
code
Example of an open channel call in an RTR client program:
status = rtr_open_channel(&Channel,
Flags,
Facility,
Recipient,
RTR_NO_PEVTNUM,
Access,
RTR_NO_NUMSEG,
RTR_NO_PKEYSEG);
if (Status != RTR_STS_OK)
Sample C server
code
Example of a receive message call in an RTR server program:
status = rtr_receive_message(&Channel,
RTR_NO_FLAGS,
RTR_ANYCHAN,
MsgBuffer,
DataLen,
RTR_NO_TIMOUTMS,
&MsgStatusBlock);
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.
