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>
