It can be useful to copy files back and forth from the host machine to a Fuchsia target. The utility in this directory keeps files in sync between the two.
To use this on the host side, add
"//src/developer/shell/mirror:sh_mirror_host"
To your build. You can then invoke the server on your host:
host-tools/sh_mirror --path=<path-to-be-mirrored> --port=<port>
It will await connections on the port, and send the contents of path to the client.
To use this on the client side, include
"//src/developer/shell/mirror:client"
In the target from which you want to call the server.
You can then client.h in your C++ program. See the APIs in that directory for more information.
