API request: Use query engine on external itemRecord

Hi, dev gurus,
I would like to be able to use the Winamp query engine on itemRecords for a file that is not in the ML. I would fill out the itemRecord struct with all the data (basic and extended data), and then call a API function with a query string and a pointer to this itemRecord. Return value would be 1 if the item matches the query rules, 0 if not, -1 if the query is invalid or any other error.

code:
typedef struct
{
char *query;
const itemRecord *ir;
} mlQueryRecordStruct;

#define ML_IPC_DB_RUNQUERY_ONRECORD 0x704 // pass mlQueryRecordStruct*



I'm sure Will will need sth. like this sooner or later for pmp_*, too (if he wants to support smart playlists)

Would that be feasable?

An second approach could be to pass in an itemRecordList, and the API call marks all items that match (it could add the indexes for matching items to a new C_ItemList, for example). That would help if you need to query thousands of tracks, it would be only one call, not thousands...

Would be really great if that could be provided. The query engine is simply too good to leave it for the ML alone
