DataSizeKeyValue

llDataSizeKeyValue

Summary

Function: key llDataSizeKeyValue( );

	Forced Delay
	Energy

Start an asynchronous transaction to request the used and total amount of data allocated for the experience.
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.

The dataserver callback parameters are:

• A key containing the handle returned from llDataSizeKeyValue
• A string containing a comma-delimited list. The first item is a boolean specifying if the transaction succeeded (1) or not (0). The second item is the amount in use, and the third value is the total. All sizes are in bytes.

Specification

Dataserver

The dataserver callback parameters are:

• A key containing the handle returned from llDataSizeKeyValue
• 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, integer used, integer quota ],",")

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.
• integer	used	–	Number of bytes used
• integer	quota	–	Number of bytes the key-store can utilize

Examples

<lsl>key trans; default {

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

}

dataserver(key t, string value) {

   if (t == trans)
   {
       // our llDataSizeKeyValue transaction is done
       list result = llCSV2List(value);
       if (llList2Integer(result, 0) == 1)
       {
           // data size retrieved
           llSay(0, "Space in use: "+llList2String(result, 1)");
           llSay(0, "Total space:  "+llList2String(result, 2)");
       }
       else
       {
           // data size check failed
           llSay(0, "Key-value failed to check size: " + llList2String(result, 1) );
       }
   }
