(v13) How the RIP communicates with a plugin

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

Most communication between the RIP and a plugin occurs when the RIP calls an exported function named PLUGIN . In most cases, when the RIP requires a task to be performed by the plugin, it calls it through this entry point with three arguments.

  • The first argument is a selector. This is a unique integer value which indicates the operation the RIP requires the plugin to perform.
  • The second argument is a pointer to the data structure representing the device that the plugin is implementing.
  • The third argument is a pointer to any further data necessary to perform the particular operation requested (it may be unused).
