iswgraph - test for graphic wide character
Návod, kniha: Linux Programmer's Manual
#include <wctype.h>
int iswgraph(wint_t wc);
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
character 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
therefore contains the wide character classes "alnum" and
"punct".
The
iswgraph function returns non-zero if
wc is a wide character
belonging to the wide character class "graph". Otherwise it returns
zero.

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