NO document for VOPNET_Node in HDK ?

[Blackstone]

Hi,

I would like to ask how to use VOPNET_Node in HDK, but there is no any info about this class, so is that possible we define a new VopNet by this class as the "RSL Surface SOHO Type" ?

I could almost guess out a basic model.

class VOPNET_OSL : public VOPNET_Node
{
public:

	VOPNET_OSL(OP_Network *parent, const char *name, OP_Operator *entry)
		:
		VOPNET_Node(parent, name, entry)
	{
	}

	~VOPNET_OSL()
	{
	}

	static OP_Node * 	myConstructor (OP_Network *, const char * name, OP_Operator * entry);
	static PRM_Template 	myTemplateList [];
};

OP_Node *
VOPNET_OSL::myConstructor(OP_Network *net, const char *name, OP_Operator *entry)
{
    return new VOPNET_OSL(net, name, entry);
}

PRM_Template		 VOPNET_OSL::myTemplateList[] = 
{
    PRM_Template()	
};

void
newVopNetOperator(OP_OperatorTable *table)
{
	OP_Operator *op = new OP_Operator("oslVopNet",
			  "OSL VOP Network",
			  VOPNET_OSL::myConstructor,
			  VOPNET_OSL::myTemplateList,
			  0,
			  0);
	table->addOperator(pOP);
}

It could appear in VEX->Custom, that's really what I want, but once create it, Houdini throws "5648: Fatal error: Segmentation Fault", and I do not what should I need to do more here, that's really a blackbox to me :'( . Is there any body know this ? Thanks for your kindly help !

Have you considered this approach? From the HDK samples:
