SIGSETMASK(2) UNIX Programmer's Manual SIGSETMASK(2) NAME sigsetmask - set current signal mask SYNOPSIS #include 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. Printed 11/26/99 September 3, 1997 1
