iswgraph(3) Library Functions Manual iswgraph(3)
NAME
iswgraph - test for graphic wide character
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <wctype.h>
int iswgraph(wint_t wc);
DESCRIPTION
The iswgraph() function is the wide-character equivalent of the is-
graph(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-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 nonzero if wc is a wide character be-
longing to the wide-character class "graph". Otherwise, it returns
zero.
