int getThreshold()

Gets the the biometric decision threshold.

return The biometric decision threshold. throws BiosealException An error has occurred during Bioseal Library execution.

## Implementation

    int getThreshold() {
      Pointer<Int> pThreshold = calloc();
      try {
        var err = biosealSDK.id3BiosealBiometricVerificationRule_GetThreshold(_pHandle.value, pThreshold);
        if (err != BiosealError.success.value) {
          throw BiosealException(err);
        }
        final vThreshold = pThreshold.value;
        return vThreshold;
      } finally {
        calloc.free(pThreshold);
      }
    }
