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 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.

ATTRIBUTES

For an explanation of the terms used in this section, see attributes (7).
