https://libwebsockets.org/pipermail/libwebsockets/2019-April/007937.html thanks to Bruce Perens for noting it. This doesn't change the intention or status of the CC0 files, they were pure CC0 before (ie, public domain) and they are pure CC0 now. It just gets rid of the (C) part at the top of the dedication which may be read to be a bit contradictory since the purpose is to make it public domain. |

lws minimal dbus client
This demonstrates nonblocking, asynchronous dbus method calls as the client.
build
Using libdbus requires additional non-default include paths setting, same as is necessary for lws build described in ./lib/roles/dbus/README.md
CMake can guess one path and the library name usually, see the README above for details of how to override for custom libdbus and cross build.
Fedora example:
$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib64/dbus-1.0/include"
$ make
Ubuntu example:
$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib/x86_64-linux-gnu/dbus-1.0/include"
$ make
usage
| Commandline option | Meaning |
|---|---|
| -d | Debug verbosity in decimal, eg, -d15 |
The minimal client connects to the minimal dbus server example, which is expected to be listening on its default abstract unix domain socket path.
It call the server Echo method with "Hello!" and returns to the event loop. When the reply comes, it prints the returned message.
Afterwards it just sits there receiving unsolicited messages from the server example, until closed by the user.
