iswctype

iswctype - wide-character classification

#include <wctype.h>
 I 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 R iswctype () function returns non-zero. Otherwise it returns zero. If wc is WEOF, zero is returned.

desc must be a character property descriptor returned by the wctype function.

The R iswctype () function returns non-zero if the wc has the designated property. Otherwise it returns 0.

C99.

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