IOCTL_FLASH_PDD_GET_BLOCK_STATUS (Compact 2013)

3/26/2014

This I/O control message queries the status of a specific block. Send this message with DeviceIoControl.

Syntax

BOOL DeviceIoControl(
    HANDLE hDevice,           // handle to the device
    DWORD dwIoControlCode,    // use IOCTL_FLASH_PDD_GET_BLOCK_STATUS
    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
    [in] Handle to the device.
  • dwIoControlCode
    [in] The control code for the operation. Use IOCTL_FLASH_PDD_GET_BLOCK_STATUS for this operation.
  • nInBufferSize
    [in] Set to the size of the FLASH_GET_BLOCK_STATUS_REQUEST structure.
  • lpOutBuffer
    [out] Array of ULONG values, where each ULONG value represents the status of the corresponding block.
  • nOutBufferSize
    [in] Size of the array of ULONG values. Specifically, it must equal sizeof(ULONG) multiplied by the BlockCount specified in the BLOCK_RUN member of the input structure.
  • lpBytesReturned
    [in] Not used; set to NULL.

Return Values

Returns nonzero if successful; otherwise, returns zero.

Remarks

To get extended error information, call GetLastError. GetLastError may return other standard error messages as appropriate.
