NAME

6       iswgraph - test for graphic wide character
7

SYNOPSIS

9       #include <wctype.h>
10
11       int iswgraph(wint_t wc);
12

DESCRIPTION

14       The  iswgraph()  function  is  the  wide-character  equivalent  of  the
15       isgraph() function. It tests whether wc is a wide  character  belonging
16       to the wide character class "graph".
17
18       The  wide  character  class "graph" is a subclass of the wide character
19       class "print".
20
21       Being a subclass of the wide character class "print", the wide  charac‐
22       ter class "graph" is disjoint from the wide character class "cntrl".
23
24       The  wide  character  class "graph" is disjoint from the wide character
25       class "space" and therefore also disjoint from its subclass "blank".
26
27       The wide character class "graph" contains all the wide characters  from
28       the  wide character class "print" except the space character. It there‐
29       fore contains the wide character classes "alnum" and "punct".

RETURN VALUE

32       The iswgraph() function returns non-zero if  wc  is  a  wide  character
33       belonging  to  the  wide  character class "graph". Otherwise it returns
34       zero.

NOTES

43       The behaviour of iswgraph() depends on the  LC_CTYPE  category  of  the
44       current locale.
