STREAMS polling and multiplexing

STREAMS polling and multiplexing

This section describes how STREAMS allows user processes to monitor, control, and poll Streams to allow an effective utilization of system resources. The synchronous polling mechanism and asynchronous event notification within STREAMS is discussed. STREAMS signal handling between modules and/or drivers and user processes is also discussed.

The remainder of this section is devoted to STREAMS input/output multiplexing. It defines a STREAMS multiplexor, and describes multiplexing drivers. A discussion of how STREAMS multiplexing configurations are created, is included. Code examples are included to illustrate using both the polling and multiplexing mechanisms.
