ISCardISO7816::GetResponse

The GetResponse method constructs an APDU command that transmits APDU commands (or part of an APDU command) which otherwise could not be transmitted by the available protocols.

HRESULT GetResponse(
  BYTE byP1,
  BYTE byP2, 
  LONG lDataLength, 
  LPSCARDCMD *ppCmd
);

Parameters

byP1, byP2 [in, defaultvalue(0)]
Per the ISO 7816-4, P1 and P2 should be 0 (RFU).
lDataLength [in, defaultvalue(0)]
Length of data transmitted.
ppCmd [in, out]
On input, a pointer to an ISCardCmd interface object or NULL.

On return, it is filled with the APDU command constructed by this operation. If ppCmd was set to NULL, a smart card ISCardCmd object is internally created and returned via the ppCmd pointer.

Return Values

The possible return values are the following:

Value Meaning
S_OK Operation completed successfully.
E_INVALIDARG Invalid parameter.
E_POINTER A bad pointer was passed in.
E_OUTOFMEMORY Out of memory.
