sigsetmask(2) BSD System Calls Manual sigsetmask(2)
NAME
sigsetmask -- set current signal mask
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <signal.h> int sigsetmask(int mask); sigmask(signum);
DESCRIPTION
This interface is made obsolete by: sigprocmask(2). Sigsetmask() sets the current signal mask. Signals are blocked from delivery if the corresponding bit in mask is a 1; the macro sigmask() is provided to construct the mask for a given signum. The system quietly disallows SIGKILL or SIGSTOP to be blocked.
RETURN VALUES
The previous set of masked signals is returned.
