Normally, the license expiration date is controlled while performing the checkout operation. However, in cases where a feature remains checked out continuously for a long period of time, this method of checking for license expiration may allow a license to be used past its expiration date.
To avoid license over-usage for such applications, we recommend that you check the value returned by the LMX_GetExpireTime API function periodically. This function gives you information about the number of hours remaining before the feature expires. When the value becomes -1, the feature is expired and you can stop the software. To continue running the software, the user must obtain a new license.
