Summary
Function: key llDeleteKeyValue( string k );
Start an asynchronous transaction to delete a key-value pair associated with the given experience key with the given key.
Returns a handle (a key) that can be used to identify the corresponding dataserver event to determine if this command succeeded or failed.
| • string | k | – | The key for the key-value pair |
The dataserver callback parameters are:
- A key containing the handle returned from llDeleteKeyValue
- 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 a string with a status/error message if it failed or the value if the transaction succeeded.
Caveats
Examples
<lsl>key trans; default {
state_entry()
{
trans = llDeleteKeyValue("FOO");
}
dataserver(key t, string value)
{
if (t == trans)
{
// our llDeleteKeyValue transaction is done
list result = llCSV2List(value);
if (llList2Integer(result, 0) == 1)
{
// the key-value pair was successfully deleted
llSay(0, "New key-value pair was deleted");
}
else
{
// the key-value pair was not deleted
llSay(0, "Key-value failed to delete: " + llList2String(result, 1) );
}
}
}
}</lsl>
