bool OEChemIsLicensed(const char *feature=0, unsigned int *expdate=0)

Determines whether a valid license file is present. This function may be called without a legitimate run-time license to determine whether it is safe to call any OEChem, OESystem or OEPlatform functionality.

The ‘features’ argument can be used to check for a valid license to OEChem along with that feature. For example, to verify that OEChem can be used from Python:

The second argument can be used to get the expiration date of the license. This is an array of size three with the date returned as {day, month, year}. Even if the function returns false due to an expired license, the ‘expdate’ will show that expiration date. A value of a zeroes implies that no license or date was found.
