INTRODUCTION
|
||
|
|
.PP
|
||
|
|
This paper describes how to write
|
||
|
|
programs
|
||
|
|
that interface with the
|
||
|
|
.UC UNIX
|
||
|
|
operating system in a non-trivial way.
|
||
|
|
This includes programs that use files by name,
|
||
|
|
that use pipes,
|
||
|
|
that invoke other commands as they run,
|
||
|
|
or that attempt to catch interrupts and other signals
|
||
|
|
during execution.

The document collects material which is scattered
|
||
|
|
throughout several sections of
|
||
|
|
.I
|
||
|
|
The
|
||
|
|
.UC UNIX
|
||
|
|
Programmer's Manual
|
||
|
|
.R
|
||
|
|
[1]
|
||
|
|
for Version 7
|
||
|
|
.UC UNIX .
|
||
|
|
There is no attempt to be complete;
|
||
|
|
only generally useful material is dealt with.
|
||
|
|
It is assumed that you will be programming in C,
|
||
|
|
so you must be able to read the language
|
||
|
|
roughly up to the level of
|
||
|
|
.I
|
||
|
|
The C Programming Language
|
||
|
|
.R
|
||
|
|
[2].
|
||
|
|
Some of the material in sections 2 through 4
|
||
|
|
is based on
|
||
|
|
topics covered more carefully there.
|
||
|
|
You should also be familiar with
|
||
|
|
.UC UNIX
|
||
|
|
itself
|
||
|
|
at least
|
||
|
|
to the level of
|
||
|
|
.I
|
||
|
|
.UC UNIX
|
||
|
|
for Beginners
|
||
|
|
.R
|
