Appendix C - The /proc Filesystem

UNIX Systems Programming for SVR4

 Copyright © 1996 O'Reilly & Associates, Inc.

Summary
This appendix has only touched on the capabilities available with the /proc filesystem. Debuggers and similar programs can use a number of other features to control the execution of a process, examine its memory, and even change its memory. For a complete set of available commands, see the proc (4) manual page.
The /proc filesystem is a substantial improvement over the old method of obtaining process information, reading kernel memory and the swap area. Not only is it simpler for the programmer to implement, it is also portable between different versions of the operating system that support /proc.
