Summary
Function: key llReadKeyValue( string k );
Start an asynchronous transaction to read the value associated with the specified key and the specified experience.
Returns the key id of the transaction.
• string | k | – | The key for the key-value pair |
The dataserver callback parameters are:
- A key containing the transaction ID returned from llReadKeyValue
- 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 = llReadKeyValue("FOO"); }
}
dataserver(key t, string value) {
if (t == trans) { // our llReadKeyValue transaction is done list result = llCSV2List(value); if (llList2Integer(result, 0) == 1) { // the key-value pair was successfully read llSay(0, "New key-value pair value: " + llList2String(1)); } else { // the key-value pair was not created llSay(0, "Key-value pair doesn't exist"); } }}</lsl>
