Integer to be tested.

Locale to use.

_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.
