STREAMS Multiplex Drivers

This chapter describes how STREAMS multiplexing configurations are created and also discusses multiplexing drivers. A STREAMS multiplexer is a driver with multiple streams connected to it. The primary function of the multiplexing driver is to switch messages among the connected streams. Multiplexer configurations are created from the user level by system calls.
