Comments
The Buffer member of DestinationString is initialized to point to SourceString. The length and maximum length
for DestinationString are initialized to the length of SourceString. If SourceString is NULL, the length is zero.
Callers of RtlInitUnicodeString can be running at IRQL <= DISPATCH_LEVEL if the DestinationString buffer is
nonpageable. Usually, callers run at IRQL = PASSIVE_LEVEL because most other RtlXxxString routines cannot
be called at raised IRQL.
