[erlang-questions] Exit status of C-port

[Olivier Girondel]

Dear all,

I have a C executable which is run with open_port (spawn_executable,
streaming binary
and getting exit_status)

If/when the C code crashes, I (most of the time) correctly get an exit message
(eg: {exit_status, 134}), which is exactly what I want.

Sometimes though, I get an "exception exit" with the reason "epipe", which means
the port really crashed in a nasty way; but this exception is not catchable.

Apart from doing this another way (-yes, I really do want to
spawn()/run a program that might crash-),
what are the options ?

Thanks,

--
Olivier

The exception you see might be that you received a exit signal from the port.
Try setting the process flag "trap_exit" to true, then you will exit signal as a message to process linked to the port.

Maybe I came back too early from my holidays in the South of France,
sorry for the noise ;)
