The UNICODE_STRING structure is used to define Unicode strings.
Syntax
typedef struct _UNICODE_STRING {
USHORT Length;
USHORT MaximumLength;
PWSTR Buffer;
} UNICODE_STRING, *PUNICODE_STRING;
Members
Length
The length, in bytes, of the string stored in Buffer.
MaximumLength
The length, in bytes, of Buffer.
Buffer
Pointer to a buffer used to contain a string of wide characters.
Remarks
The UNICODE_STRING structure is used to pass Unicode strings. Use RtlUnicodeStringInit or RtlUnicodeStringInitEx to initialize a UNICODE_STRING structure.
If the string is null-terminated, Length does not include the trailing null character.
The MaximumLength is used to indicate the length of Buffer so that if the string is passed to a conversion routine such as RtlAnsiStringToUnicodeString the returned string does not exceed the buffer size.
