Request License (QLZAREQ) API

The Request License (QLZAREQ) API requests the use of a product that has been packaged for licensed use. Multiple uses of a product may be requested with a single call to this API. The request causes the usage count to be compared with the usage limit. The uses are assigned to the name that is specified in the license user parameter. The uses remain assigned to the license user until they are released (see

Note: It is suggested that before a Request License (QLZAREQ) is done, the application retrieves the product information handle using the Retrieve License Information API (QLZARTV). The application should then compare this handle with the handle passed back at Add Product License Information time. It should compare the two values before the Request is done. If the handles do not match, the product has been tampered with. This process helps to ensure asset protection.
