NAME

       iswgraph - test for graphic wide character

LIBRARY

       Standard C library (libc, -lc)

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.
