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.

     rent locale.
