IOCTL_STORAGE_FIRMWARE_GET_INFO IOCTL (winioctl.h)

  • Article

Windows applications can use this control code to query the storage device for detailed firmware information. A successful call will return information about firmware revisions, activity status, as well as read/write attributes for each slot. The amount of data returned will vary based on storage protocol.

To perform this operation, call the DeviceIoControl function with the following parameters.

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