1# lws minimal dbus client 2 3This demonstrates nonblocking, asynchronous dbus method calls as the client. 4 5## build 6 7Using libdbus requires additional non-default include paths setting, same as 8is necessary for lws build described in ./lib/roles/dbus/README.md 9 10CMake can guess one path and the library name usually, see the README above 11for details of how to override for custom libdbus and cross build. 12 13Fedora example: 14``` 15$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib64/dbus-1.0/include" 16$ make 17``` 18 19Ubuntu example: 20``` 21$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib/x86_64-linux-gnu/dbus-1.0/include" 22$ make 23``` 24 25## usage 26 27Commandline option|Meaning 28---|--- 29-d <loglevel>|Debug verbosity in decimal, eg, -d15 30 31The minimal client connects to the minimal dbus server example, which is 32expected to be listening on its default abstract unix domain socket path. 33 34It call the server Echo method with "Hello!" and returns to the event loop. 35When the reply comes, it prints the returned message. 36 37Afterwards it just sits there receiving unsolicited messages from the server 38example, until closed by the user. 39 40``` 41 $ ./lws-minimal-dbus-client 42ctx 43[2018/10/05 06:08:31:4901] NOTICE: pending_call_notify 44[2018/10/05 06:08:31:4929] USER: pending_call_notify: received 'Hello!' 45^C[2018/10/05 06:09:22:4409] NOTICE: destroy_dbus_client_conn 46[2018/10/05 06:09:22:4691] NOTICE: Exiting cleanly 47... 48``` 49 50
