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 functions tests a given multibyte character for a given condition.
