Changes the partition type of the specified disk partition. (Floppy drivers need not handle this request.)
Major code
Input buffer
The buffer at Irp->AssociatedIrp.SystemBuffer contains the SET_PARTITION_INFORMATION to be set.
Input buffer length
Parameters.DeviceIoControl.InputBufferLength in the I/O stack location of the IRP indicates the size, in bytes, of the buffer, which must be >= sizeof(SET_PARTITION_INFORMATION).
Output buffer
None.
Output buffer length
None.
Status block
The Information field is set to zero. The Status field can be set to STATUS_SUCCESS, or possibly to STATUS_INVALID_PARAMETER, STATUS_INVALID_DEVICE_REQUEST, STATUS_UNSUCCESSFUL, STATUS_INFO_LENGTH_MISMATCH, STATUS_INSUFFICIENT_RESOURCES, or STATUS_BUFFER_TOO_SMALL.
