It tests whether \fIwc\fP is a wide character belonging to the wide-character class "graph". .PP The wide-character class "graph" is a subclass of the wide-character class "print". .PP Being a subclass of the wide-character class "print", the wide-character class "graph" is disjoint from the wide-character class "cntrl". .PP The wide-character class "graph" is disjoint from the wide-character class "space" and therefore also disjoint from its subclass "blank". .\" Note: UNIX98 (susv2/xbd/locale.html) says that "graph" and "space" may .\" have characters in common, except U+0020. But C99 (ISO/IEC 9899:1999 .\" section 7.25.2.1.10) says that "space" and "graph" are disjoint. .PP 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". .SH "RETURN VALUE" The .BR iswgraph () function returns non-zero if \fIwc\fP is a wide character belonging to the wide-character class "graph". Otherwise it returns zero. .SH "CONFORMING TO" C99. .SH NOTES The behavior of .BR iswgraph () depends on the .B LC_CTYPE category of the current locale. .SH "SEE ALSO" .BR isgraph (3), .BR iswctype (3)
