.\"O .SH DESCRIPTION
.SH 説明
.\"O The
.\"O .BR iswspace ()
.\"O function is the wide-character equivalent of the
.\"O .BR isspace (3)
.\"O function.
.\"O It tests whether \fIwc\fP is a wide character
.\"O belonging to the wide-character class "space".
.BR iswspace ()
関数は、
.BR isspace (3)
に対応するワイド文字関数である。
この関数は、\fIwc\fP がワイド文字クラス "space" に属するワイド文字かど
うかを調べる。
.PP
.\"O The wide-character class "space" is disjoint from the wide-character class
.\"O "graph" and therefore also disjoint from its subclasses "alnum", "alpha",
.\"O "upper", "lower", "digit", "xdigit", "punct".
ワイド文字クラス "space" はワイド文字クラス "graph" と共通部分を持たない。
したがって、そのサブクラスである "alnum", "alpha", "upper", "lower",
"digit", "xdigit", "punct" とも共通部分を持たない。
.\" Note: UNIX98 (susv2/xbd/locale.html) says that "space" and "graph" 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
.\"O The wide-character class "space" contains the wide-character class "blank".
ワイド文字クラス "space" はワイド文字クラス "blank" を含む。
.PP
.\"O The wide-character class "space" always contains at least the space character
.\"O and the control
.\"O characters \(aq\\f\(aq, \(aq\\n\(aq, \(aq\\r\(aq, \(aq\\t\(aq, \(aq\\v\(aq.
ワイド文字クラス "space" は少なくとも、空白文字および制御文字 \(aq\\f\(aq,
\(aq\\n\(aq, \(aq\\r\(aq, \(aq\\t\(aq, \(aq\\v\(aq を必ず含む。
.\"O .SH "RETURN VALUE"
.SH 返り値
.\"O The
.\"O .BR iswspace ()
.\"O function returns nonzero if \fIwc\fP is a wide character
.\"O belonging to the wide-character class "space".
.\"O Otherwise it returns zero.
.BR iswspace ()
関数は、\fIwc\fP がワイド文字クラス "space" に含まれる
ならば 0 でない値を返す。そうでなければ 0 を返す。

.\"O .SH NOTES
.SH 注意
.\"O The behavior of
.\"O .BR iswspace ()
.\"O depends on the
.\"O .B LC_CTYPE
.\"O category of the
.\"O current locale.
