[erlang-questions] gen_server and the run-time errors

[Gilberto Carmenate García]

Hi, info

well, try to try catch the line
ets:insert(?MODULE,{Pid,0}),  <<<< this line provokes the shutdown
or simple catch

you got shutdown reason at the end because for the supervisor the only
matter is the gen_server final state so, and its state was shutdown
because any error was threw under its initialization, so to know and print
what error was try the try..catch clause 

try
    ets:insert(?MODULE,{Pid,0}),  <<<< this line provokes the shutdown
of

catch 
    Error:Reason->
        io:format("Error: ~p  Reason: ~p", [Error, Reason])
end.

or something like that.


Best,

Ivan.
