# POE::Component::Resolver::Sidecar(3pm)

delegate subprocess to call getaddrinfo()

## NAME

POE::Component::Resolver::Sidecar - delegate subprocess to call getaddrinfo()

## VERSION

version 0.921

## SYNOPSIS

Used internally by POE::Component::Resolver.

## DESCRIPTION

POE::Component::Resolver creates subprocesses to call **getaddrinfo()** so that the main program doesn't block during that time.

The actual **getaddrinfo()** calling code is abstracted into this module so it can be run in a separate executable program.  This reduces the memory footprint of forking the entire main process for just **getaddrinfo()**.

It's a strong, useful pattern that other POE::Components have implemented before.  POE::Quickie does it generically. POE::Component::SimpleDBI and POE::Component::EasyDBI do it so their DBI subprocesses are relatively lightweight.

### main

The main code to read POE::Component::Resolver requests from STDIN and write **getaddrinfo()** responses to STDOUT.

## SEE ALSO

POE::Component::Generic is one generic implementation of this pattern.

POE::Quickie is another generic implementation of this pattern.

## BUGS

None known.
