Summary

Function: key llDataSizeKeyValue( );

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.

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);
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

Caveats

  • If you recompile a script that was previously associated with an Experience but do so with a client that lacks the ability to compile scripts into an experience the script will loose the associated Experience.

Examples

key trans;
 
default
{
    state_entry()
    {
        trans = llDataSizeKeyValue();
    }
 
    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 ) );
            }
        }
    } 
}

Notes

Compiling

For a script to be associated with an Experience...

  • It must be compiled with a client that is Experience aware,
  • The "Use Experience" checkbox must be checked,
  • And one of the users Experience keys selected.
