Gets the mouth occlusion threshold. If the mouth occlusion score is above this value, the mouth is probably occluded. Hint: Default value 70.

return Mouth occlusion threshold. throws FaceException An error has occurred during Face Library execution.

## Implementation

    int getMouthOcclusionThreshold() {
      Pointer<Int> pMouthOcclusionThreshold = calloc();
      try {
        var err = faceSDK.id3FacePortraitProcessor_GetMouthOcclusionThreshold(_pHandle.value, pMouthOcclusionThreshold);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vMouthOcclusionThreshold = pMouthOcclusionThreshold.value;
        return vMouthOcclusionThreshold;
      } finally {
        calloc.free(pMouthOcclusionThreshold);
      }
    }
