iswctype - wide-character classification

  #include <wctype.h>

  int iswctype(wint_t wc, wctype_t desc);

If wc is a wide character having the character property designated by desc (or in other words: belongs to the character class designated by desc), the iswctype*() function returns nonzero. Otherwise, it returns zero. If wc is *WEOF, zero is returned.

desc must be a character property descriptor returned by the *wctype*(3) function.

The *iswctype*() function returns nonzero if the wc has the designated property. Otherwise, it returns 0.

For an explanation of the terms used in this section, see *attributes*(7).

POSIX.1-2001, POSIX.1-2008, C99.

The behavior of iswctype*() depends on the *LC_CTYPE category of the current locale.
