.SH "DESCRIPTION"
.PP
The \fBrtlinux_sigsetops\fP(3) functions allow the manipulation
of RTLinux signal sets, similar to \fBsigsetops\fP(3).
.PP
\fBrtlinux_sigemptyset\fP initializes the set given by
\fBset\fR to empty, with all signals excluded from the set.
.PP
\fBrtlinux_sigfillset\fP initializes the set given by
\fBset\fR to full, including all signals.
.PP
\fBrtlinux_sigaddset\fP and
\fBrtlinux_sigdelset\fP add and delete, respectively, signal
\fBsignum\fR from \fBset\fR.
.PP
\fBrtlinux_sigismember\fP tests whether
\fBsignum\fR is a member of \fBset\fR.
.SH "RETURN VALUES"
.PP
\fBrtlinux_sigemptyset\fP,
\fBrtlinux_sigfullset\fP,
\fBrtlinux_sigaddset\fP, and
\fBrtlinux_sigdelset\fP return 0 on success and -1 on error.
.PP
\fBrtlinux_sigismember\fP returns 1 if
\fBsignum\fR is a member of \fBset\fR, 0 if
\fBsignum\fR is not a member, and -1 on error.
.SH "ERRORS"
.IP "EINVAL" 10
\fBsig\fR is not a valid
signal.
.SH "AUTHOR"
.PP
