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



NAME
       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).

       It is not possible to block SIGSTOP or SIGKILL.
