llDeleteKeyValue

Summary

Function: key llDeleteKeyValue( string k );

	Forced Delay
	Energy

Start an asynchronous transaction to delete a key-value pair associated with the given experience key with the given key.
Returns a handle (a key) that can be used to identify the corresponding dataserver event to determine if this command succeeded or failed and the results.

• string

k

–

The key for the key-value pairThe key for the key-value pair

Specification

Dataserver

The dataserver callback parameters are:

• A key containing the handle returned from llDeleteKeyValue
• A string containing a comma-delimited list (cdl). llDumpList2String([ integer success ] + components);
  • components vary depending upon success or failure of request.
  • Failure: cdl = llDumpList2String([ 0, integer error],",")
  • Success: cdl = llDumpList2String([ 1, string value ],",")

String Components

• integer	success	–	A boolean specifying if the transaction succeeded (1) or not (0).
• integer	error	–	An XP_ERROR_* flag that describes why the operation failed.
• string	value	–	The value for the key-value pair. Maximum 2047 characters, or 4095 if using Mono. Note! This value may contain commas.

Examples

<lsl>key trans; default {

   state_entry()
   {
       trans = llDeleteKeyValue("FOO");
   }

   dataserver(key t, string value)
   {
       if (t == trans)
       {
           // our llDeleteKeyValue transaction is done
           list result = llCSV2List(value);
           if (llList2Integer(result, 0) == 1)
           {
               // the key-value pair was successfully deleted
               llSay(0, "New key-value pair was deleted");
           }
           else
           {
               // the key-value pair was not deleted
               llSay(0, "Key-value failed to delete: " + llList2String(result, 1) );
           }
       } 
   }
