NAME

6       sigsetmask - set current signal mask
7

SYNOPSIS

9       #include <signal.h>
10
11       omask = sigsetmask(mask);
12       long omask, mask;
13
14       mask = sigmask(signum)
15       long mask;
16       int signum;
17

DESCRIPTION

19       This interface is made obsolete by:
20
21       Sigsetmask sets the current signal mask (those signals that are blocked
22       from delivery).  Signals are blocked if the corresponding bit  in  mask
23       is a 1; the macro sigmask is provided to construct the mask for a given
24       signum.
25
26       The system  quietly  disallows  SIGKILL,  SIGSTOP,  or  SIGCONT  to  be
27       blocked.
28

RETURN VALUE

30       The previous set of masked signals is returned.
