.SH NAME
POE::Component::Resolver::Sidecar \- delegate subprocess to call getaddrinfo()
.SH VERSION
.IX Header "VERSION"
version 0.921
.SH SYNOPSIS
.IX Header "SYNOPSIS"
Used internally by POE::Component::Resolver.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
POE::Component::Resolver creates subprocesses to call \fBgetaddrinfo()\fR so
that the main program doesn't block during that time.
.PP
The actual \fBgetaddrinfo()\fR 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
\&\fBgetaddrinfo()\fR.
.PP
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.
.SS main
.IX Subsection "main"
The main code to read POE::Component::Resolver requests from STDIN and
write \fBgetaddrinfo()\fR responses to STDOUT.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
POE::Component::Generic is one generic implementation of this
pattern.
.PP
POE::Quickie is another generic implementation of this pattern.
.SH BUGS
.IX Header "BUGS"
None known.
