IOCTL_FLASH_PDD_LOCK_BLOCKS (Compact 2013)
3/26/2014
This I/O control message locks one or more contiguous ranges of physical blocks; such that block cannot be unlocked without a power reset. If support for block locking is desired, then this I/O control message must be implemented. Send this message with DeviceIoControl.
Syntax
BOOL DeviceIoControl(
HANDLE hDevice, // handle to the device
DWORD dwIoControlCode, // use IOCTL_FLASH_PDD_LOCK_BLOCKS
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_LOCK_BLOCKS for this operation.
- lpInBuffer
[in] Pointer to an array of BLOCK_RUN structures. Each element of the array specifies a single run of blocks to lock. All other blocks should be unlocked.
- nInBufferSize
[in] Size of the BLOCK_RUN structure multiplied by the number of elements in the array.
- lpOutBuffer
Not used; set to NULL.
- nOutBufferSize
Not used; set to zero.
- lpBytesReturned
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.
