int _ismbbalnum(
   unsigned int c 
);
int _ismbbalnum_l(
   unsigned int c 
);

Parameters

  • c
    Integer to be tested.

  • locale
    Locale to use.

Return Value

_ismbbalnum returns a nonzero value if the expression:

isalnum || _ismbbkalnum

is nonzero for c, or 0 if it is not.

The version of this function with the _l suffix is identical except that it uses the locale passed in instead of the current locale for its locale-dependent behavior.
