POSIX::SigSet - collect signal flags
use POSIX::SigSet ();
use POSIX::1003::Signals;
$sigset = POSIX::SigSet->new;
$sigset = POSIX::SigSet->new(SIGUSR1);
$sigset->addset(SIGUSR2);

if( $sigset->ismember(SIGUSR1) ) { ... }
The POSIX::SigSet object is simple a collection of signal flags. The object is administered in POSIX.xs. See POSIX::SigAction for examples of its usage.
Create a new SigSet object. One or more SIGNALS can be added immediately. The object will be destroyed automatically when it is no longer needed.
Add one signal to a SigSet object. Returns undef on failure.
Remove one signal from the SigSet object. Returns undef on failure.
Initialize the SigSet object to be empty. Returns undef on failure.
Initialize the SigSet object to include all signals. Returns undef on failure.
Tests the SigSet object to see if it contains a specific signal.
example:
if($sigset->ismember(SIGUSR1)) {
print "contains SIGUSR1\n";
}
