.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"
