Send Feedback

The SmartcardDeviceControl function is the main entry function for the smart card driver library. It performs parameter checking and completes calls that do not require I/O with the smart card reader.

NTSTATUS SmartcardDeviceControl(PSMARTCARD_EXTENSION SmartcardExtension,PBYTE pInBuf,DWORD nInBufSize,PBYTE pOutBuf,DWORD nOutBufSize,PDWORD pBytesReturned);

Parameters

  • SmartcardExtension
    [in] Points to the smart card structure of the driver.
  • pInBuf
    [in] Same as the driver entrypoint PSC_DeviceIOControlpInBuf parameter.
  • nInBufSize
    [in] Same as the driver entrypoint PSC_DeviceIOControlnInBufSize parameter.
  • pOutBuf
    [out] Same as the driver entrypoint PSC_DeviceIOControlpOutBuf parameter.
  • nOutBufSize
    [out] Same as the driver entrypoint PSC_DeviceIOControlnOutBufSize parameter.
  • pBytesReturned
    [out] Same as the driver entrypoint PSC_DeviceIOControlpBytesReturned parameter.

Return Values

SmartcardDeviceControl returns the NTSTATUS value of the called routine.

Remarks

The driver's XXX_IOControl (Device Manager) routine must call this function to let the library check parameters and complete calls that do not need to do I/O with the reader.

The smart card driver library checks the version of the SMARTCARD_EXTENSION structure. Before calling SmartcardDeviceControl, the driver must assign to the Version member of SMARTCARD_EXTENSION the value SMCLIB_VERSION. This is usually done in the PSC_Deinit routine.

Requirements

OS Versions: Windows CE 3.0 and later.
Header: Smclib.h.
