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.

Parameter

c

Character to be tested

Remarks

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

Routine	Test Condition	Code Page 932 Example
_ismbcalnum	Alphanumeric	Returns true if and only if c is a single-byte representation of an ASCII English letter: See examples for _ismbcdigit and _ismbcalpha.
_ismbcalpha	Alphabetic	Returns true if and only if c is a single-byte representation of an ASCII English letter: 0x41<=c<=0x5A or 0x61<=c<=0x7A; or a Katakana letter: 0xA6<=c<=0xDF.
_ismbcdigit	Digit	Returns true if and only if c is a single-byte representation of an ASCII digit: 0x30<=c<=0x39.
