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-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 nonzero  if  wc  is  a  wide  character
       belonging  to  the wide-character class "graph".  Otherwise, it returns
       zero.

NOTES
       The behavior of iswgraph() depends on the LC_CTYPE category of the cur-
       rent locale.
