|func=is_uuid<br />
|func_desc=Created by [[User:Peter Stindberg|Peter Stindberg]], this function will take a [[key]] as input and return TRUE or FALSE depending on wether the key is a valid Second Life agent [[UUID]]. There are two formal checks there for key-length and number of dashes in the string. <syntaxhighlight lang="lsl">integer is_uuid(key uuid) {<br />
return (<br />
(llStringLength(uuid) == 36) <br />
&& (llGetSubString(uuid, 14, 14) == "4")<br />
&& (llGetListLength(llParseString2List(uuid, ["-"], [])) == 5)<br />
);<br />
}</syntaxhighlight><br />

|caveats=The function checks for a signal that is widely believed to be only part of agent UUID's and not object UUID's. Extensive tests by [[User:Peter Stindberg|Peter Stindberg]] as well as other users have shown no counter-example up to date. There is no guarantee that is true for all agent UUID's, nor that it won't change in the future.<br />
