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) func-
       tion.  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 non-zero if wc is a wide character belonging to the
       wide-character class "graph".  Otherwise it returns zero.

CONFORMING TO
       C99.

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