NAME

       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];

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 nec-
	   essary 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").
