Interpretation of Multibyte-Character Sequences

Most multibyte-character routines in the Microsoft run-time library recognize multibyte-character sequences relating to a multibyte code page. The output value is affected by the setting of the LC_CTYPE category setting of the locale; see setlocale for more information. The versions of these functions without the _l suffix use the current locale for this locale-dependent behavior; the versions with the _l suffix are identical except that they use the locale parameter passed in instead.

Locale-Dependent Multibyte Routines

Routine	Use
_mbclen, mblen, _mblen_l	Validate and return number of bytes in multibyte character
strlen, wcslen, _mbslen, _mbslen_l, _mbstrlen, _mbstrlen_l	For multibyte character strings: validate each character in string; return string length. For wide character strings: return string length.
mbstowcs, _mbstowcs_l, mbstowcs_s, _mbstowcs_s_l	Convert sequence of multibyte characters to corresponding sequence of wide characters
mbtowc, _mbtowc_l	Convert multibyte character to corresponding wide character
wcstombs, _wcstombs_l, wcstombs_s, _wcstombs_s_l	Convert sequence of wide characters to corresponding sequence of multibyte characters
wctomb, _wctomb_l, wctomb_s, _wctomb_s_l	Convert wide character to corresponding multibyte character
