IPC::Signal: Utility functions dealing with signals

SYNOPSIS

    $number = sig_num $name;
    $name   = sig_name $number;

sig_translate_setup; $number = $Sig_num{$name}; $name = $Sig_name[$number];

This module contains utility functions for dealing with signals.

Nothing is exported by default.

sig_num chopped-signal-name: Returns the signal number of the signal whose name (sans \*(C`SIG\*(C') is chopped-signal-name, or undef if there is no such signal. This function is prototyped to take a single scalar argument.
sig_name signal-number: Returns the chopped signal name (like \*(C`HUP\*(C') of signal number signal-number, or undef if there is no such signal. This function is prototyped to take a single scalar argument.
sig_translate_setup: If you want to use the @Sig_name and %Sig_num variables directly you must call sig_translate_setup to initialize them. This isn't necessary if you only use the function interfaces sig_name() and sig_num(). This function is prototyped to take no arguments.
%Sig_num: A hash with chopped signal name keys (like \*(C`HUP\*(C') and integer signal number values.
@Sig_name: An array mapping signal numbers to chopped signal names (like \*(C`HUP\*(C').
