This section introduces asynchronous network communication, using sockets or Transport-Level Interface (TLI) for real-time applications. Asynchronous networking with sockets is done by setting an open socket, of type SOCK_STREAM, to asynchronous and non blocking. For more information on asynchronous sockets, see Advanced Socket Topics. Asynchronous network processing of TLI events is supported using a combination of STREAMS asynchronous features and the non-blocking mode of the TLI library routines.
For more information on the Transport-Level Interface, see Chapter 8, Programming With XTI and TLI.
