NBD — Network Block Device — is a protocol for accessing Block Devices
(hard disks and disk-like things) over a Network.

nbdkit is a toolkit for creating NBD servers.

This directory contains the cross-compiled Windows binaries, updated
irregularly.  The license is BSD-like.  For sources, see:

  https://github.com/libguestfs/nbdkit/

To test if it works, you will need to download at a minimum:

 - nbdkit.exe (the server)
 - nbdkit-memory-plugin.dll (the RAM disk plugin)
 - libdl.dll, libgnutls.dll, libwinpthread.dll from mingw-w64

Then try:

  nbdkit.exe -f -v nbdkit-memory-plugin.dll 1G

You should be able to connect an NBD client to TCP port 10809.
Windows 10 has a firewall so you may also need to open this port.

The other most useful plugin is nbdkit-file-plugin.dll for serving
regular files and Windows volumes.

The *.a and *.h files are for developing your own plugins.  There is a
simple Windows plugin example here:
