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 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").
