Plugin interface version information

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

Version information is obtained on the first call from the RIP to the plugin, using the D_GET_IDENTITY selector. This selector is now implemented in input and output plugins.

The D_GET_IDENTITY selector passes the plugin an IdentityParam structure, with the version information fields: pluginInterfaceMajorVersion , and pluginInterfaceMinorVersion , filled in by the RIP; and fVersionOK , which should be filled in by the plugin to inform the RIP whether or not the plugin can run with this version of the interface. See D_GET_IDENTITY for full details of how this should be done.
