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. ATTRIBUTES
