_ismbbalpha, _ismbbalpha_l

Determines whether a specified multibyte character is alpha.

Syntax

int _ismbbalpha(
   unsigned int c
);
int _ismbbalpha_l(
   unsigned int c
);

Parameters

c
Integer to be tested.

locale
Locale to use.

Return value

_ismbbalpha returns a nonzero value when the expression:

isalpha(c) || _ismbbkalnum(c)

is nonzero for c, or 0 when the expression is zero. _ismbbalpha uses the current locale for any locale-dependent character settings. _ismbbalpha_l is identical except that it uses the locale passed in.

Remarks

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