Summary
Function: key llCreateKeyValue( string k, string v );
Start an asynchronous transaction to create a key-value pair associated with the given experience key using the given key and value.
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 | |
| • string | v | – | The value for the key-value pair. Maximum 2047 characters, or 4095 if using Mono. |
Will fail with XP_ERROR_STORAGE_EXCEPTION if the key already exists.
The dataserver callback parameters are:
- A key containing the handle returned from llCreateKeyValue
- 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 {
touch_start(integer total_number)
{
trans = llCreateKeyValue("FOO", "BAR");
}
dataserver(key t, string value)
{
if (t == trans)
{
// our llCreateKeyValue transaction is done
integer result = (integer)llGetSubString(value, 0, 0);
if (result == 1)
{
// the key-value pair was successfully created
llSay(0, "New key-value pair was created");
}
else
{
// the key-value pair was not created
integer error = (integer)(llGetSubString(value, 2, -1));
llSay(0, "Key-value failed to create: " + llGetExperienceErrorMessage(error));
}
}
}
}</lsl>
