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
       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  charac-
       ter 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 there-
       fore contains the wide character classes "alnum" and "punct".

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

NOTES
       The behaviour of iswgraph depends on the LC_CTYPE category of the  cur-
       rent locale.
