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

       sgetmask, ssetmask - manipulation of signal mask (obsolete)

       long sgetmask(void);

       long ssetmask(long newmask);

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

       These  system  calls are obsolete.  Do not use them; use sigprocmask(2)

       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.

       sgetmask()  always  successfully  returns  the signal mask.  ssetmask()
       always succeeds, and returns the previous signal mask.

       These system calls always succeed.

       These system calls are Linux-specific.

       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 signals).

       These system calls do not exist on x86-64.

       It is not possible to block SIGSTOP or SIGKILL.

       sigprocmask(2), signal(7)
