(v13) D_CMM_QUERY (core module plugins)

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

D_CMM_QUERY Selector

Parameter: CoreModuleQueryParam * param

Call type: Single call

This call is made to determine the number of Color Management Core Modules that this plugin contains. The number should be returned in n_instances .

The plugin can inspect api_version to determine if it is compatible with the RIP by comparing its API version (taken from the enumeration sw_cmm_api_versions in swcmm.h ) to that presented by the RIP.

This can be used, for instance, to ensure that use of the sw_message_fn function is not attempted with RIPs which report SW_HTM_API_VERSION_20071110 and earlier.

    typedef struct CoreModuleQueryParam {
      int32 api_version ; /* (I) RIP's API version */
      int32 n_instances ; /* (O) how many instances the plugin supports */
    } CoreModuleQueryParam ;
