IPC::Signal(3) 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];

DESCRIPTION

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 "SIG") 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 "HUP") 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 "HUP") and integer signal number values.
@Sig_name
An array mapping signal numbers to chopped signal names (like "HUP").
