ISWCTYPE(3)                Linux Programmer's Manual               ISWCTYPE(3)
NAME
       iswctype - wide-character classification
SYNOPSIS
       #include <wctype.h>
       int iswctype(wint_t wc, wctype_t desc);
DESCRIPTION
       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
       The  iswctype()  function  returns nonzero if the wc has the designated
       property.  Otherwise, it returns 0.

       rent locale.
