ISCardISO7816::AppendRecord method
[The AppendRecord method is available for use in the operating systems specified in the Requirements section. It is not available for use in Windows Server 2003 with Service Pack 1 (SP1) and later, Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The Smart Card Modules provide similar functionality.]
The AppendRecord method constructs an application protocol data unit (APDU) command that either appends a record to the end of a linear-structured elementary file (EF) or writes record number 1 in a cyclic-structured elementary file.
Syntax
HRESULT AppendRecord(
[in] BYTE byRefCtrl,
[in] LPBYTEBUFFER pData,
[in, out] LPSCARDCMD *ppCmd
);
Parameters
-
byRefCtrl [in]
-
Identifies the elementary file to be appended.
Value Meaning - Current EF
Bit position: 00000000 - Short EF ID
Bit position: xxxxx000 - Reserved
Bit position: xxxxxxxx -
pData [in]
-
A pointer to the data to be appended to the file.
Value Meaning - Tn
1 byte - Ln
1 or 3 bytes - data
Ln bytes -
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 by using the ppCmd pointer.
Return value
The method returns one of the following possible values.
| Return code | Description |
|---|---|
|
Operation completed successfully. |
|
Invalid parameter. |
|
A bad pointer was passed in. |
|
Out of memory. |
Remarks
The encapsulated command can only be performed if the security status of the smart card satisfies the security attributes of the elementary file read.
If another elementary file is selected at the time of issuing this command, it may be processed without identification of the currently selected file.
Elementary files without a record structure cannot be read. The encapsulated command aborts if applied to an elementary file without a record structure.
For a list of all the methods provided by this interface, see ISCardISO7816.
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 more information, see Smart Card Return Values.
