   _locale_t locale
);

_strninc and _wcsninc are single-byte–character string and wide-character string versions of _mbsninc. _wcsninc and _strninc are provided only for this mapping and should not be used otherwise. For more information, see Using Generic-Text Mappings and Generic-Text Mappings.

_mbsninc_l is identical except that it uses the locale parameter passed in instead. For more information, see Locale.
