ISWGRAPH(3) Linux Programmer's Manual ISWGRAPH(3)NAMEiswgraph - 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() 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 non-zero if wc is a wide character
belonging to the wide character class "graph". Otherwise it returns
zero.
CONFORMING TO
C99.

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