# Lintian::IO::Async(3)

process functions based on IO::Async

## NAME

Lintian::IO::Async - process functions based on IO::Async

## SYNOPSIS

```
 use Lintian::IO::Async qw(safe_qx);
```

## DESCRIPTION

This module contains process functions based on IO::Async.

## FUNCTIONS

- "safe\_qx(@cmd)"

  Emulates the `"qx()"` operator but with array argument only.

- get\_deb\_info(DEBFILE)

  Extracts the control file from DEBFILE and returns it as a hashref.

  DEBFILE must be an ar file containing a "control.tar.gz" member, which in turn should contain a "control" file.  If the "control" file is empty this will return an empty list.

  Note: the control file is only expected to have a single paragraph and thus only the first is returned (in the unlikely case that there are more than one).

- unpack\_and\_index\_piped\_tar
