Defined in header <cwctype>
std::wctype_t wctype( const char* str );

Constructs a value of type std::wctype_t that describes a LC_CTYPE category of wide character classification. It may be one of the standard classification categories, or a locale-specific category, such as "jkanji".

Parameters

str

-

C string holding the name of the desired category

The following values of str are supported in all C locales:

value of str	effect
"alnum"	identifies the category used by std::iswalnum
"alpha"	identifies the category used by std::iswalpha
"blank"	identifies the category used by std::iswblank (C++11)
"cntrl"	identifies the category used by std::iswcntrl
"digit"	identifies the category used by std::iswdigit
"graph"	identifies the category used by std::iswgraph
"lower"	identifies the category used by std::iswlower
"print"	identifies the category used by std::iswprint
"space"	identifies the category used by std::iswspace
"upper"	identifies the category used by std::iswupper
"xdigit"	identifies the category used by std::iswxdigit

Return value

std::wctype_t object suitable for use with std::iswctype to classify wide characters according to the named category of the current C locale or zero if str does not name a category supported by the current C locale.
