NAME

Linux::Pdeathsig - Perl interface to request a signal on parent death

SYNOPSIS

  use Linux::Pdeathsig;

  set_pdeathsig(9);
  # now you will get SIGKILL when the parent process ends

  my $v = &get_pdeathsig;
  # get the signal that will be sent when the parent process ends

DESCRIPTION

This simple module provides two functions to set or get the signal that the linux kernel will send when the parent process dies. get_pdeathsig returns 0 when no signal has been set. set_pdeathsig(0) will clear the setting. Both functions croak on error.

EXPORTS

set_pdeathsig, get_pdeathsig by default.
