The PutData method constructs an APDU command that stores a single primitive data object or the set of data objects contained in a constructed data object, depending on the file selected.
How the objects are stored (writing once and/or updating and/or appending) depends on the definition or the nature of the data objects.
HRESULT PutData(
BYTE byP1,
BYTE byP2,
LPBYTEBUFFER pData,
LPSCARDCMD *ppCmd
);
Value | Meaning |
---|---|
0000 - 003F | RFU |
0040 - 00FF | BER-TLV tag (1 byte) in P2 |
0100 - 01FF | Application data (proprietary coding) |
0200 - 02FF | SIMPLE-TLV tag in P2 |
0300 - 03FF | RFU |
0400 - 04FF | BER-TLV tag (2 bytes) in P1-P2 |
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.
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. |
The command can be performed only if the security status satisfies the security conditions defined by the application within the context for the function.
When the value of P1-P2 lies in the range 0200 to 02FF, the value of P2 shall be a SIMPLE-TLV tag. The value 0200 is RFU. The value 02FF is reserved for indicating that the data field carries SIMPLE-TLV data objects.
When the value of P1-P2 lies in the range from 4000 to FFFF, the value of P1-P2 shall be a BER-TLV tag on two bytes. The values 4000 to FFFF are RFU.
When a primitive data object is provided, the data field of the command message shall contain the value of the corresponding primitive data object.
When a constructed data object is provided, the data field of the command message shall contain the value of the constructed data object (that is, data objects including their tag, length, and value).

In addition to the COM error codes listed above, this interface may return a smart card error code if a smart card function was called to complete the request. For information on smart card error codes, see Error Codes.
