Important note Important

This API cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported with /ZW.

unsigned int _mbctombb(
   unsigned int c 
unsigned int _mbctombb_l(
   unsigned int c,
   _locale_t locale


Multibyte character to convert.


Locale to use.

If successful, _mbctombb and _mbctombb_lreturns the single-byte character that corresponds to c; otherwise it returns c.

The _mbctombb and _mbctombb_lfunctions convert a given multibyte character to a corresponding single-byte multibyte character. Characters must correspond to single-byte characters within the range 0x20 – 0x7E or 0xA1 – 0xDF to be converted.

The output value is affected by the setting of the LC_CTYPE category setting of the locale; see setlocale for more information. The version of this function without the _l suffix uses the current locale for this locale-dependent behavior; the version with the _l suffix is identical except that it use the locale parameter passed in instead. For more information, see Locale.

In previous versions, _mbctombb was called zentohan. Use _mbctombb instead.
