Partitions a disk according to the specified drive layout and partition information data.
To perform this operation, call the DeviceIoControl function with the following parameters.
BOOL DeviceIoControl( (HANDLE) hDevice, // handle to device IOCTL_DISK_SET_DRIVE_LAYOUT_EX, // dwIoControlCode(LPVOID) lpInBuffer, // input buffer (DWORD) nInBufferSize, // size of the input buffer NULL, // lpOutBuffer0, // nOutBufferSize (LPDWORD) lpBytesReturned, // number of bytes returned (LPOVERLAPPED) lpOverlapped // OVERLAPPED structure );
Input buffer length
Output buffer length
Input / Output buffer
Input / Output buffer length
Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful.
Otherwise, Status to the appropriate error condition as a NTSTATUS code.
For more information, see NTSTATUS Values.
When specifying a GUID partition table (GPT) as the PARTITION_STYLE of the CREATE_DISK structure, an application should wait for the MSR partition arrival before sending the IOCTL_DISK_SET_DRIVE_LAYOUT_EX control code. For more information about device notification, see RegisterDeviceNotification.
When creating and manipulating an Extended Boot Record (EBR), the first entry of the EBR should point to the logical drive that immediately follows the EBR and the next EBR should lie after the end of the current logical drive and before the start of the next logical drive.
If the partition is on a disk formatted as type master boot record (MBR), partition size totals are limited. For more information, see the Remarks section of IOCTL_DISK_SET_DRIVE_LAYOUT.
