# IPC::Signal(3pm)

Utility functions dealing with signals

## 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"`).
