[pulseaudio-discuss] Detecting success/error in cli protocol?

(apologies for sending an incomplete mail earlier)
is there a way to detect that a CLI command has succeeded or failed when
using the socket interface offered by module-cli-protocol-unix?
Specifically I'm currently interested in the "play-file" command (which
seems to be only accessible over the CLI interface). If the command
fails because the daemon can't read the file, there is no error message
returned back through the socket. Any error is only written to syslog.
In general I don't see any way of getting back the success/error status
of a command. pulse-cli-syntax man page does not mention anything in
this regard. "pacmd" also does not signal failures through its exit code.
I see that individual handlers in cli-command.c (including
pa_cli_command_play_file) return -1 on error, but this status seems to
be lost somewhere down the line. Is see that in line_callback() in cli.c
the return value of pa_cli_command_execute_line() is ignored.
Does anyone have any thoughts on how proper error handling could be
implemented in the cli interface? I would be happy to work on a patch to
