NAME
iswgraph - 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(3)
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".
RETURN VALUE
The
iswgraph()
function returns nonzero
if
wc
is a wide character
belonging to the wide-character class "graph".
Otherwise, it returns zero.
