-
implemented interprocess communications (IPC) are key to the performance of
virtually every non

trivial UNIX program. In
UNIX Network
Programming,
Udnme
2,
Seeond
Edition,
legendary UNIX expert W. Richard Stevens presents
a comprehensive guide to every form of
IPC. including message passing. synchronization.
shared memory, and Remote Procedure Calls (RPG.

Stevens heglns with a basic: introduction to IPC and the problems it is intended
to
solve
Slep

step you'll learn how to maximize both System
V
IPC and the new Posix standards.
which offer dramatic improvements in convenience and performance. You'll find extensive
coverage of Pthreads. with many examples rrflecting multiple threads instead of multiple
processes.
Alongthe way. you'll master every current IPC technique and technology. including:
Pipes and
FlFOs
POSIX and System

Semaphores
Posix and System

You'll actually create implemkntatiom of Posix message queues.

of
these
capabilities you simply can't get

The book contains extensive new source code

all caqfully optimized and available
on the Web. You'll even find
a
complete guide
to
mesuring IPC performance
with message passing bandwidth and
laterfcy progrMns, and thread and process
synchronization programs.
The better you understand
IPC. the better your UNIX software will run. This book
contains all you need to know.
