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);- 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) );
}
}
}</lsl>
