Summary
Function: key llKeyCountKeyValue( );
Start an asynchronous transaction to request the number of keys in the system.
Returns a handle (a key) that can be used to identify the corresponding dataserver event to determine if this command succeeded or failed.
The dataserver callback parameters are:
- A key containing the handle returned from llKeyCountKeyValue
- A string containing a comma-delimited list. The first item is a boolean specifying if the transaction succeeded (1) or not (0). On a success result the second value is the number of items in the system.
Caveats
Examples
<lsl>key trans; default {
state_entry() { trans = llKeyCountKeyValue("FOO"); }
}
dataserver(key t, string value) {
if (t == trans) { // our llKeyCountKeyValue transaction is done list result = llCSV2List(value); if (llList2Integer(result, 0) == 1) { // data size retrieved llSay(0, "Keys in use: "+llList2String(result, 1)"); } else { // key count failed llSay(0, "Key-value failed to count keys: " + llList2String(result, 1) ); } }}</lsl>
