Summary

Function: list llLinksetDataDeleteFound( string pattern, string pass );

0.0	Forced Delay
10.0	Energy

The llLinksetDataDeleteFound function finds and attempts to delete all keys in the data store that match pattern. This function will delete protected key-value pairs only if the matching pass phrase is passed in the pass parameter. The function returns a list, the first entry in the list is the number of keys deleted, the second entry in the list is the number of keys that could not be deleted due to a non-matching pass phrase. If this function successfully deletes any keys from the datastore it will trigger a linkset_data event with the type of LINKSET_DATA_MULTIDELETE, the key name will consist of a comma separated list of the key names removed from the datastore.
Returns a list of the number of keys deleted or skipped.

• string	pattern	–	A regular expression describing which keys to delete.
• string	pass	–	Optional pass phrase to delete protected keys.
