Hi everyone,

I am trying to check in a daemon, with liblaunch. But I am always getting a IPC failure.
For now I just tried the samplecode in sampled.c

It's just creating a launch_data_t wiht launch_data_new_string(LAUNCH_KEY_CHECKIN);  and tries to get a response (launch_msg(msg))) but that returns a NULL and no response. 

Could somebody give me a hint how to do that.
