It tests whether \fIwc\fP is a wide character +belonging to the wide character class "space". +.PP +The wide character class "space" is disjoint from the wide character class +"graph" and therefore also disjoint from its subclasses "alnum", "alpha", +"upper", "lower", "digit", "xdigit", "punct". +.\" Note: UNIX98 (susv2/xbd/locale.html) says that "space" and "graph" 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 "space" contains the wide character class "blank". +.PP +The wide character class "space" always contains at least the space character +and the control characters '\\f', '\\n', '\\r', '\\t', '\\v'. +.SH "RETURN VALUE" +The \fBiswspace\fP function returns non-zero if \fIwc\fP is a wide character +belonging to the wide character class "space". Otherwise it returns zero. +.SH "CONFORMING TO" +ISO/ANSI C, UNIX98 +.SH "SEE ALSO" +.BR isspace (3), +.BR iswctype (3) +.SH NOTES +The behaviour of \fBiswspace\fP depends on the LC_CTYPE category of the +current locale. |
