CheckInExtension

Résumé

Returns the license to the License Manager so other applications can use it.

Discussion

Remarque :

CheckInExtension is only needed when using a Concurrent Use license; for all other cases it has no effect. When using a Concurrent Use license, once the extension license has been retrieved by the script, tools using that extension can be used. Once a script is finished with an extension's tools, the CheckInExtension function should be used to return the license to the License Manager so other applications can use it. All checked-out extension licenses and set product licenses are returned to the License Manager when a script completes.
