CentOS 7.0 - man page for sgetmask (centos section 2)

SGETMASK(2)			    Linux Programmer's Manual			      SGETMASK(2)

NAME
       sgetmask, ssetmask - manipulation of signal mask (obsolete)

SYNOPSIS
       long sgetmask(void);

       long ssetmask(long newmask);

       Note: There are no glibc wrappers for these system calls; see NOTES.

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 obsolete system calls;  in  the  unlikely  event
       that you want to call them, use syscall(2).

       These  system  calls  are  unaware of signal numbers greater than 31 (i.e., real-time sig-
       nals).

       It is not possible to block SIGSTOP or SIGKILL.

SEE ALSO
       sigprocmask(2), signal(7)
