Conventions used in this manual

This page applies to Harlequin v13.1r0 and later; and to Harlequin MultiRIP but not Harlequin Core

All conventions are explained as they are first used. Here are some widely‐used conventions.

Selectors

How the RIP communicates with a plugin explains how the RIP calls plugins with an argument called a selector , always starting with the form D_... It is simpler, however, to describe a call to the plugin with a particular selector among the arguments as calling that selector. Rather than saying:

The RIP calls the plugin with the selector D_INITIALISE ... It is easier to say this:

The RIP calls D_INITIALISE ...

Structure fields

In descriptions of structures used by plugins, each field is classified using the following letters, according to the type of access which can be made by the plugin and the RIP. These letters are shown on the right of the page, next to the name of the field.
