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
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.

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