1 .RtlInitEmptyUnicodeString The RtlInitEmptyUnicodeString macro initializes an empty counted Unicode string. VOID RtlInitEmptyUnicodeString( IN OUT PUNICODE_STRING DestinationString, IN PCWSTR Buffer, IN USHORT BufferSize ); Parameters DestinationString Pointer to the UNICODE_STRING structure to be initialized. Buffer Pointer to a caller-allocated buffer to be used to contain a WCHAR string. BufferSize Length, in bytes, of the buffer pointed to by Buffer. Return Value None Headers Declared in ntifs.h. Include ntifs.h. Comments This macro is available on Microsoft Windows XP and later. The members of DestinationString are initialized as follows: Member Value Length Zero MaximumLength BufferSize Buffer SourceString To initialize a nonempty counted Unicode string, call RtlInitUnicodeString. Callers of RtlInitEmptyUnicodeString can be running at any IRQL. 2.
