NAME

6       iswctype - wide-character classification
7

SYNOPSIS

9       #include <wctype.h>
10
11       int iswctype(wint_t wc, wctype_t desc);
12

DESCRIPTION

14       If  wc  is a wide character having the character property designated by
15       desc (or in other words: belongs to the character class  designated  by
16       desc),  the iswctype() function returns nonzero.  Otherwise, it returns
17       zero.  If wc is WEOF, zero is returned.
18
19       desc must be a character property descriptor returned by the  wctype(3)
20       function.
21

RETURN VALUE

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