SIGSETMASK(2)           COMMAND REFERENCE           SIGSETMASK(2)



NAME
     sigsetmask - set current signal mask

SYNOPSIS
     omask = sigsetmask(mask);
     int omask;
     int mask;

DESCRIPTION
     Sigsetmask sets the current signal mask (those signals which
     are blocked from delivery) to mask. Signal i is blocked if
     the i-th bit in mask is a 1.  Bits are numbered beginning at
     1.

     The system quietly disallows SIGKILL, SIGSTOP, or SIGCONT to
     be blocked.

RETURN VALUE
     The previous set of masked signals is returned in omask.

CAVEATS
     As noted above, bits are numbered beginning at 1, not 0.

SEE ALSO
     kill(2), sigblock(2), sigpause(2), and sigvec(2).
