LSA_STRING structure (lsalookup.h)

  • Article

The LSA_STRING structure is used by Local Security Authority (LSA) functions to specify an ANSI string.

Syntax

typedef struct _LSA_STRING {
  USHORT Length;
  USHORT MaximumLength;
  PCHAR  Buffer;
} LSA_STRING, *PLSA_STRING;

Members

Length

Specifies the length, in bytes, of the string in Buffer. This value does not include the terminating null character, if any.

When the Length structure member is zero and the MaximumLength structure member is 1, the Buffer structure member must not be an empty string or contain solely a null character.

Windows 7, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP:  When the Length structure member is zero and the MaximumLength structure member is 1, the Buffer structure member can be an empty string or contain solely a null character. This behavior changed beginning with Windows Server 2008 R2 and Windows 7 with SP1.

MaximumLength

Specifies the total size, in bytes, of Buffer. Up to MaximumLength bytes may be written into the buffer without trampling memory.

When the Length structure member is zero and the MaximumLength structure member is 1, the Buffer structure member must not be an empty string or contain solely a null character.

Windows 7, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP:  When the Length structure member is zero and the MaximumLength structure member is 1, the Buffer structure member can be an empty string or contain solely a null character. This behavior changed beginning with Windows Server 2008 R2 and Windows 7 with SP1.

Buffer

Pointer to an array of characters. Note that strings returned by the LSA may not be null-terminated.

When the Length structure member is zero and the MaximumLength structure member is 1, the Buffer structure member must not be an empty string or contain solely a null character.

Windows 7, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP:  When the Length structure member is zero and the MaximumLength structure member is 1, the Buffer structure member can be an empty string or contain solely a null character. This behavior changed beginning with Windows Server 2008 R2 and Windows 7 with SP1.
