IOCTL_FLASH_LOCK_PARTITIONS (Compact 2013)
3/26/2014
This I/O control message locks one or more partitions, such that blocks can not be unlocked without a power reset. All other partitions on store will be unlocked. This I/O control message allows for regions that are not contiguous to be locked, but the flash part may not support this behavior. Send this message with DeviceIoControl.
Syntax
BOOL DeviceIoControl(
HANDLE hDevice, // handle to the device
DWORD dwIoControlCode, // use IOCTL_FLASH_LOCK_PARTITIONS
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_LOCK_PARTITIONS for this operation.
- lpInBuffer
[in] Pointer to an array of PARTITION_ID structures. Each element of the array specifies a partition identifier to lock.
- nInBufferSize
[in] Size of the PARTITION_ID structure multiplied by the number of elements in the array.
- lpOutBuffer
[in] Not used; set to NULL.
- nOutBufferSize
[out] Not used; set to zero.
- 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.
