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

Determine 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 of OESpruce’s functionality.

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

if not OESpruceIsLicensed("python"):
    print "OESpruce is not licensed for the python feature"
expdate = OEUIntArray(3)
if OESpruceIsLicensed(0, expdate):
  print "License expires: day: %d  month: %d year: %d"%
               (expdate[0], expdate[1], expdate[2])
