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.

CONFORMING TO

NOTES

   The behavior of iswgraph() depends on  the  LC_CTYPE  category  of  the
   current locale.
