_UNICODE_STRING structure

The UNICODE_STRING structure is used to define Unicode strings.

Syntax

typedef struct _UNICODE_STRING {
  USHORT Length;
  USHORT MaximumLength;
  PWCH   Buffer;
} UNICODE_STRING;

Members

Length

The length, in bytes, of the string stored in Buffer.

MaximumLength

The length, in bytes, of Buffer.

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.

Requirements

   
Header wudfwdm.h (include Wdm.h, Ntddk.h, Ntdef.h)
