Chapter 5
The GETOPTS unit.

This document describes the GETOPTS unit for Free Pascal. It was written for LINUX by Michaël Van Canneyt. It now also works for all supported platforms.

The getopts unit provides a mechanism to handle command-line options in a structured way, much like the GNU getopts mechanism. It allows you to define the valid options for you program, and the unit will then parse the command-line options for you, and inform you of any errors.

The chapter is divided in 2 sections:

• The first section lists types, constants and variables from the interface part of the unit.
• The second section describes the functions defined in the unit.
