about SAFEARRAY** and the VTS_UNKNOWN type

I'm trying to call the HMPSVD method below (it is created
by a 3d party tool and it accesses a mainframe).
//////////////////////////////////////////////////////////
class CVariantArr : public COleDispatchDriver
{
public:
CVariantArr(){} // Calls COleDispatchDriver
default constructor
CVariantArr(LPDISPATCH pDispatch) :
COleDispatchDriver(pDispatch) {}
CVariantArr(const CVariantArr& dispatchSrc) :
COleDispatchDriver(dispatchSrc) {}
// Attributes
public:
// Operations
public:
// _VariantArr methods
public:
long HMPSVD(SAFEARRAY * * HMP10XC, long * tpurcode)
{
long result;
static BYTE parms[] = VTS_UNKNOWN VTS_PI4 ;
InvokeHelper(0x1, DISPATCH_METHOD, VT_I4,
(void*)&result, parms, HMP10XC, tpurcode);
return result;
}
// _VariantArr properties
public:
};
/////////////////////////////////////////////////////////
There shall be 2 parameters in the varuant array
long p1;
char array p2;
I cannot figure out how to set up the array and to call
the method.
The SAFEARRAY * * is causing me problems. The VTS_UNKNOWN is wrong I think. And I tried to change it into VTS_I2 or VTS_VARIANT. It didn't work.
Any suggestions?? Thanks.
