SIGSETMASK(2)	    UNIX Programmer's Manual	    SIGSETMASK(2)



NAME
     sigsetmask - set current signal mask

SYNOPSIS
     #include <signal.h>

     omask = sigsetmask(mask);
     long omask, mask;

     mask = sigmask(signum)
     long mask;
     int signum;

DESCRIPTION
     This interface is made obsolete by:

     _S_i_g_s_e_t_m_a_s_k sets the current signal mask (those signals that
     are blocked from delivery).  Signals are blocked if the
     corresponding bit in _m_a_s_k is a 1; the macro _s_i_g_m_a_s_k is pro-
     vided to construct the mask for a given _s_i_g_n_u_m.

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

RETURN VALUE
     The previous set of masked signals is returned.

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

HISTORY
     The sigsetmask function call appeared in 4.2BSD and has been
     deprecated.
