Chapter 19: STREAMS Drivers

STREAMS programming in SVR4.2 is documented in STREAMS Modules and Drivers, UNIX SVR4.2. That book contains detailed discussion and many examples of STREAMS programming.

References in this chapter to STREAMS Modules and Drivers are to the edition copyright 1992 by UNIX System Laborartories, published by UNIX Press/Prentice-Hall, and bearing ISBN 0-13-066879. If you are using an earlier edition, you should upgrade it. If you have a later edition, you may have to interpret references carefully.

This chapter contains the following major sections:

• "Driver Exported Names" summarizes the public names and functions that a STREAMS driver must export.

• "Building and Debugging" describes the ways that building a STREAMS driver are like and unlike other kernel-level drivers.

• "Special Considerations for Multiprocessing" describes the methods you must use to work with the multi-threaded STREAMS monitor.

• "Special Considerations for IRIX" details the points at which IRIX differs from the SVR4 STREAMS environment.

• "Summary of Standard STREAMS Functions" lists the available kernel functions used by STREAMS drivers.

• "STREAMS Modules for X Input Devices" describes the use of configuration files for special input devices used by the X display manager.
