_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.
