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.
