Character to be tested.

Locale to use.

Return Value

Each of these routines returns a nonzero value if the character satisfies the test condition or 0 if it does not. If c <= 255 and there is a corresponding _ismbb routine (for example, _ismbcalnum corresponds to _ismbbalnum), the result is the return value of the corresponding _ismbb routine.


Each of these functions tests a given multibyte character for a given condition.

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.

Routine Test condition (code page 932 only)
_ismbcl0 JIS non-Kanji: 0x8140<=c<=0x889E.
_ismbcl0_l JIS non-Kanji: 0x8140<=c<=0x889E.
_ismbcl1 JIS level-1: 0x889F<=c<=0x9872.
_ismbcl1_l JIS level-1: 0x889F<=c<=0x9872.
_ismbcl2 JIS level-2: 0x989F<=c<=0xEAA4.
_ismbcl2_l JIS level-2: 0x989F<=c<=0xEAA4.

The functions check that the specified value c matches the test conditions described above, but do not check that c is a valid multibyte character. If the lower byte is in the ranges 0x00 - 0x3F, 0x7F, or 0xFD - 0xFF, these functions return a nonzero value, indicating that the character satisfies the test condition. Use _ismbbtrail to test whether the multibyte character is defined.
