# [NAME](#NAME)

IPC::Run::Win32Pump - helper processes to shovel data to/from parent, child

# [SYNOPSIS](#SYNOPSIS)

Internal use only; see IPC::Run::Win32IO and best of luck to you.

# [DESCRIPTION](#DESCRIPTION)

See IPC::Run::Win32Helper for details. This module is used in subprocesses that are spawned to shovel data to/from parent processes from/to their child processes. Where possible, pumps are optimized away.

NOTE: This is not a real module: it's a script in module form, designed to be run like

```
   $^X -MIPC::Run::Win32Pumper -e 1 ...
```

It parses a bunch of command line parameters from IPC::Run::Win32IO.
