IOCTL_SMARTCARD_GET_ATTRIBUTE (Windows Embedded CE 6.0)

1/6/2010

This code queries smart card and smart card reader attributes. For a list of all defined attributes, refer to Part 3 of the Interoperability Specification for ICCs and Personal Computer Systems.

Parameters

• dwOpenData
  [in] Handle returned from a call to the smart card reader driver's XXX_Open (Device Manager) function.

• dwCode
  [in] Specifies this code.

• pBufIn
  [in] Contains a tag value describing the data to be retrieved.

• dwLenIn
  [in] Must be set to sizeof(ULONG).

• pBufOut
  [out] The attribute data.

• dwLenOut
  [out] The size of the output buffer, which receives the attribute data. The size depends on the attribute.

• pdwActualOut
  [out] The actual number of bytes returned, not counting terminating NULL characters in strings.

Return Values

The status value STATUS_SUCCESS or STATUS_NOT_SUPPORTED, as appropriate.

Remarks

Smart card reader drivers return Windows NT status values, rather than Win32 error values, as the return values from the driver's callback function.
