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 is‐
15       graph(3) 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".
30

RETURN VALUE

32       The iswgraph() function returns nonzero if wc is a wide  character  be‐
33       longing  to  the  wide-character  class "graph".  Otherwise, it returns
34       zero.

NOTES

50       The behavior of iswgraph() depends on the LC_CTYPE category of the cur‐
51       rent locale.
