The D_SELECTOR_SUPPORT selector

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

  D_SELECTOR_SUPPORT Selector
    Parameter: int32 * selector

The RIP calls this to test whether the plugin supports a given selector. Because the RIP can call this selector to check for other selectors before calling them, the plugin interface can be extended in newer RIPs without affecting the operation of existing plugins: if the RIP finds that plugin does not support a particular selector, it can call another one that it does support.

The parameter (the third parameter to be passed to the PLUGIN function with the selector) is a pointer to a selector value. If the plugin implements that selector, it returns NOERR , otherwise it returns ‐1.

See D_SELECTOR_SUPPORT for more details.
