In other words, it represents a class of wide characters. This type's nature is implementation dependent, but the special value ''(wctype_t)0'' denotes an invalid property. Nonzero __wctype_t__ values can be passed to the __iswctype__ function to actually test whether a given wide character has the property. The __wctype__ function returns a property, given by its name. The set of valid names depends on the LC_CTYPE category of the current locale, but the following names are valid in all locales. isalnum__ classification function __isalpha__ classification function __isblank__ classification function __iscntrl__ classification function __isdigit__ classification function __isgraph__ classification function __islower__ classification function __isprint__ classification function __ispunct__ classification function __isspace__ classification function __isupper__ classification function __isxdigit__ classification function !!RETURN VALUE The __wctype__ function returns a property descriptor if the ''name'' is valid. Otherwise it returns ''(wctype_t)0''. !!CONFORMING TO ISO/ANSI C, UNIX98 !!SEE ALSO iswctype(3) !!NOTES The behaviour of __wctype__ depends on the LC_CTYPE category of the current locale. ----
