NAME
       iswprint - test for printing wide character

SYNOPSIS
       #include <wctype.h>

       int iswprint(wint_t wc);

DESCRIPTION
       The  iswprint() function is the wide-character equivalent of the isprint(3) function.  It tests whether wc is a wide character belonging to
       the wide-character class "print".

       The wide-character class "print" is disjoint from the wide-character class "cntrl".

       The wide-character class "print" contains the wide-character class "graph".

RETURN VALUE
       The iswprint() function returns nonzero if wc is a wide character belonging to the wide-character class	"print".   Otherwise,  it  returns
       zero.
