  $sigset->addset(SIGUSR2);
  $sigset->delset(SIGUSR2);
  $sigset->emptyset();
  $sigset->fillset();
  if( $sigset->ismember(SIGUSR1) ) { ... }

DESCRIPTION

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.

METHODS

Constructors

POSIX::SigSet->new([SIGNALS])

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.

Other

$obj->addset(SIGNAL)

Add one signal to a SigSet object. Returns undef on failure.

$obj->delset(SIGNAL)

Remove one signal from the SigSet object. Returns undef on failure.

$obj->emptyset()

Initialize the SigSet object to be empty. Returns undef on failure.

$obj->fillset()

Initialize the SigSet object to include all signals. Returns undef on failure.

$obj->ismember()

Tests the SigSet object to see if it contains a specific signal.

example:

  if($sigset->ismember(SIGUSR1)) {
      print "contains SIGUSR1\n";
  }
