String Manipulation

These routines operate on null-terminated single-byte character, wide-character, and multibyte-character strings. Use the buffer-manipulation routines, described in Buffer Manipulation, to work with character arrays that do not end with a null character.

String-Manipulation Routines

Routine	Use
_mbscoll, _mbsicoll, _mbsncoll, _mbsnicoll	Compare two multibyte-character strings using multibyte code page information (_mbsicoll and _mbsnicoll are case-insensitive)
