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.
