Character to convert.


Locale to use.

On Japanese locale, these functions return a converted character or return 0 if no conversion is possible. On a non-Japanese locale, these functions return the character passed in.

The _mbcjistojms function converts a Japan Industry Standard (JIS) character to a Microsoft Kanji (Shift JIS) character. The character is converted only if the lead and trail bytes are in the range 0x21 – 0x7E. If the lead or trial byte is outside this range, errno is set to EILSEQ. For more information about this and other error codes, see errno, _doserrno, _sys_errlist, and _sys_nerr.

The _mbcjmstojis function converts a Shift JIS character to a JIS character. The character is converted only if the lead byte is in the range 0x81 – 0x9F or 0xE0 – 0xFC and the trail byte is in the range 0x40 – 0x7E or 0x80 – 0xFC. Note that some code points in that range do not have a character assigned and so cannot be converted.

The value c should be a 16-bit value whose upper 8 bits represent the lead byte of the character to convert and whose lower 8 bits represent the trail byte.

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. For more information, see Locale.

In earlier versions, _mbcjistojms and _mbcjmstojis were calledjistojms and jmstojis, respectively. _mbcjistojms, _mbcjistojms_l, _mbcjmstojis and _mbcjmstojis_l should be used instead.
