Trying to work out if a polygon bounding box contains a point... (cocos2dx / c++)

So far this line gets the Bounding attachment...

spBoundingBoxAttachment *boundat = (spBoundingBoxAttachment *)this->panAnim->getAttachment("pan1bounds", "pan1bounds");

i assume i need to do something like

auto bounds = spSkeletonBounds_getPolygon(????, boundat);

then

spSkeletonBounds_aabbContainsPoint(bounds, 0, 0);

but not sure how to get the spSkeletonBounds for the spSkeletonBounds_getPolygon...

Hope you can help...

Thanks

Update: ok this rough bit of code works, however am i getting the sbBoundingPolygon the best way possible?

Note: the /4, *2 & *4 are due to spine not interpreting content scale factor

bool BookPage7Scene::isPointInBounds(Point location, const char *boneNamme, const char *slotName, const char *attachmentName)
{
    Size visibleSize = Director::getInstance()->getVisibleSize();
    spBone *pan1bone = this->panAnim->findBone(boneNamme);
    spBoundingBoxAttachment *boundingAttachment = (spBoundingBoxAttachment *)this->panAnim->getAttachment(slotName, attachmentName);
    auto boundingPolygon = spBoundingPolygon_create(boundingAttachment->verticesCount);
    for (int i = 0; i<boundingAttachment->verticesCount; i++) {
        boundingPolygon->vertices[i]=boundingAttachment->vertices[i] / 4;
        boundingPolygon->count+=1;
    }
    spBoundingBoxAttachment_computeWorldVertices(boundingAttachment, visibleSize.width * 2, visibleSize.height * 2, pan1bone, boundingPolygon->vertices);
    bool clicked = spBoundingPolygon_containsPoint(boundingPolygon, location.x * 4, location.y * 4);
    spBoundingPolygon_dispose(boundingPolygon);
    return clicked;
}
