_mbcjistojms, _mbcjistojms_l, _mbcjmstojis, _mbcjmstojis_l

Converts between Japan Industry Standard (JIS) and Japan Microsoft (JMS) characters.

Syntax

unsigned int _mbcjistojms(
   unsigned int c
);
unsigned int _mbcjistojms_l(
   unsigned int c,
   _locale_t locale
);
unsigned int _mbcjmstojis(
   unsigned int c
);
unsigned int _mbcjmstojis_l(
   unsigned int c,
   _locale_t locale
);

Parameters

c
Character to convert.

locale
Locale to use.

Return value

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.

Remarks

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. Some code points in that range don't have a character assigned, and so can't 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. For more information, see setlocale. 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 called jistojms and jmstojis, respectively. _mbcjistojms, _mbcjistojms_l, _mbcjmstojis and _mbcjmstojis_l should be used instead.

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.
