Using an external unix filter

[Carsten Schultz]

Hi,

how can I close the stdin of a spawned port and still collect its
output?  I would like to do something like


Port = open_port({spawn, SOME_UNIX_FILTER}, [exit_status, binary]),
Port ! {self(), {command, Data}},
SOMEHOW TELL THE PORT I WILL NOT SEND MORE DATA,
collect_loop(Port, []).

collect_loop(Port, Acc) ->
    receive
	M={Port, {data, Bin}} ->
	    collect_loop(Port, [Acc, Bin]);
	M={Port, _} ->
	    Acc
    end.


Thanks in advance,

Carsten
