_ismbbalnum, _ismbbalnum_l

Determines whether a specified multibyte character is alpha or numeric.

Syntax

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 when the expression:

isalnum(c) || _ismbbkalnum(c)

is nonzero for c, or 0 when the expression is zero.

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.

Remarks

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.

Requirements
