NAME

IPC::Signal - Utility functions dealing with signals

CONTENTS

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.
<B>sig_numB> 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.

<B>sig_nameB> 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.

<B>sig_translate_setupB> If you want to use the @Sig_name and %Sig_num variables directly you must call <B>sig_translate_setupB> 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.

<B>B>%Sig_num<B>B> A hash with chopped signal name keys (like HUP) and integer signal number values.
<B>B>@Sig_name<B>B> An array mapping signal numbers to chopped signal names (like HUP).
