IrDA (Infrared Data Association) support is implemented as an Exchange Manager plug-in (see Exchange Manager in the Programming Guide).

The IrDA plug-in is responsible for routing data transfer requests from the client to the destination Exchange daemon, where they are dispatched to the right handler. The plug-in handles an incoming request by handing it to the exchange daemon, waiting for the execution result from the handler, and sending back the response. The IrDA plug-in also manages compatibility with sending and receiving standard OBEX objects.

For more information about the Exchange Manager, see the Programming Guide.
