SIGSETMASK(2) UNIX Programmer's Manual SIGSETMASK(2) NAME sigsetmask - set current signal mask SYNOPSIS #include <signal.h> sigsetmask(mask); int mask; mask = sigmask(signum) DESCRIPTION _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.
