ISWCTYPE(3)             Linux Programmer's Manual            ISWCTYPE(3)

NAME         top

       iswctype - wide-character classification

SYNOPSIS         top

       #include <wctype.h>

       int iswctype(wint_t wc, wctype_t desc);

DESCRIPTION         top

       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.

RETURN VALUE         top

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