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.



Character to be tested


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

Routine Test Condition Code Page 932 Example
_ismbclegal Valid multibyte Returns true if and only if the first byte of c is within ranges 0x81 – 0x9F or 0xE0 – 0xFC, while the second byte is within ranges 0x40 - 0x7E or 0x80 - FC.
_ismbcsymbol Multibyte symbol Returns true if and only if 0x8141<=c<=0x81AC.
