This I/O control message returns the bus driver version. Send this message with DeviceIoControl.

Syntax

BOOL DeviceIoControl(
    HANDLE hDevice,           // handle to device
    DWORD dwIoControlCode,    // use IOCTL_SD_BUS_DRIVER_GET_VERSION
    LPVOID lpInBuffer,        // pointer to input buffer
    DWORD nInBufferSize,      // input buffer size
    LPVOID lpOutBuffer,       // pointer to output buffer
    DWORD nOutBufferSize,     // output buffer size
    LPDWORD lpBytesReturned,  // number of bytes returned
    OVERLAPPED lpOverlapped   // pointer to OVERLAPPED structure
);

Parameters

  • hDevice
    The handle to the bus driver.
  • dwIoControlCode

    [out] Pointer to a DWORD variable that contains the current version number of the bus driver. The upper 16 bits represent the version major. The lower 16 bits represent the version minor.
  • nOutBufferSize
    [in] Size of the value pointed to by lpOutBuffer.
  • lpBytesReturned
    [out] Pointer to a DWORD variable to return the length of returned data. If there is no error, set to sizeof(DWORD).
  • lpOverlapped
    Ignored.
