.\"O .SH DESCRIPTION
.SH 説明
.PP
.\"O .BR sigpending ()
.\"O returns the set of signals that are pending for delivery to the calling
.\"O thread (i.e., the signals which have been raised while blocked).
.\"O The mask of pending signals is returned in
.\"O .IR set .

.\"O .SH "RETURN VALUE"

.\"O The set of signals that is pending for a thread
.\"O is the union of the set of signals that is pending for that thread
.\"O and the set of threads that is pending for the process as a whole; see
.\"O .BR signal (7).
あるスレッドに対する処理待ちのシグナルの集合は、
そのスレッド自体への処理待ちのシグナル集合と、プロセス全体への処理待ちの
シグナル集合をあわせたものである。

.\"O A child created via
.\"O .BR fork (2)
.\"O initially has an empty pending signal set;
.\"O the pending signal set is preserved across an
.\"O .BR execve (2).

.\"O .SH BUGS
.SH バグ
.\"O In versions of glibc up to and including 2.2.1,
.\"O there is a bug in the wrapper function for
.\"O .BR sigpending ()
.\"O which means that information about pending real-time signals
.\"O is not correctly returned.
バージョン 2.2.1 以前の glibc では、
.BR sigpending ()
のラッパー関数に、処理待ちのリアルタイムシグナルに関する情報が
正しく返されないというバグがある。
