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 ISO 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 \fBiswgraph\fP 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" +ISO/ANSI C, UNIX98 +.SH "SEE ALSO" +.BR isgraph (3), +.BR iswctype (3) +.SH NOTES +The behaviour of \fBiswgraph\fP depends on the LC_CTYPE category of the +current locale. |
