OnixS C++ FIX Engine  3.24.0
API Documentation

OnixS C++ FIX Engine requires a valid license key file for its execution. If there is no license file available or C++ FIX Engine is not able to locate it, OnixS::FIX::Exception will be thrown.

Locating License

By default, C++ FIX Engine looks for the license file(s) in the current working directory and then looks for the license in the user home directory.

However, your license file can be placed anywhere on the file system. To instruct C++ FIX Engine about an alternative location of the license file, it's necessary to specify the path to the folder which contains license file(s), using LicenseStore configuration setting. You can specify more than one license store, symbol '|' is used as the license store delimiter.

Also, you can specify the license content directly using LicenseString configuration setting.

The LicenseFile configuration setting is deprecated as of FIX Engine 2.76.1.0.

License Expiration

Expiration date can be checked by opening the license file in a text editor or by calling the Engine::licenseExpirationDate() method.
