_ismbcalnum, _ismbcalpha, _ismbcdigit
int _ismbcalnum( unsigned int c ); int _ismbcalpha( unsigned int c ); int _ismbcdigit( unsigned int c );
- Character to be tested.
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 routines tests a given multibyte character for a given condition.
|Routine||Test condition||Code page 932 example|
|_ismbcalnum||Alphanumeric||Returns nonzero if and only if c is a single-byte representation of an ASCII English letter: See examples for _ismbcdigit and _ismbcalpha.|
|_ismbcalpha||Alphabetic||Returns nonzero 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 nonzero if and only if c is a single-byte representation of an ASCII digit: 0x30<=c<=0x39.|
