sgetmask, ssetmask - manipulation of signal mask (obsolete)
SYNOPSIS
long sgetmask(void);
long ssetmask(long newmask);
DESCRIPTION
These system calls are obsolete.
Do not use them;
use
sigprocmask(2)
instead.
sgetmask()
returns the signal mask of the calling process.
ssetmask()
sets the signal mask of the calling process to the value given in
newmask.
The previous signal mask is returned.
The signal masks dealt with by these two system calls
are plain bit masks (unlike the
sigset_t
used by
sigprocmask(2));
use
sigmask(3)
to create and inspect these masks.
RETURN VALUE
sgetmask()
always successfully returns the signal mask.
ssetmask()
always succeeds, and returns the previous signal mask.
ERRORS
These system calls always succeed.
CONFORMING TO
These system calls are Linux-specific.
NOTES
Glibc does not provide wrappers for these system calls; use
syscall(2).
These system calls are unaware of signal numbers greater than 31
(i.e., real-time signals).

man-pages
