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

NAME
       iswgraph - test for graphic wide character

SYNOPSIS
       #include <wctype.h>

       int iswgraph(wint_t wc);

DESCRIPTION
       The  iswgraph()  function  is  the wide-character equivalent of the isgraph(3) function.  It tests whether wc is a wide character belonging to the wide-character
       class "graph".

       The wide-character class "graph" is a subclass of the wide-character class "print".

       Being a subclass of the wide-character class "print", the wide-character class "graph" is disjoint from the wide-character class "cntrl".

       The wide-character class "graph" is disjoint from the wide-character class "space" and therefore also disjoint from its subclass "blank".

       The wide-character class "graph" contains all the wide characters from the wide-character class "print" except the space character.  It  therefore  contains  the
       wide-character classes "alnum" and "punct".

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