[erlang-questions] Pass Name to Dynamic Supervisors
Thu Sep 8 10:44:34 CEST 2011
I managed this when writing an OS erlang app recently.
in the supervisor:
and in the worker:
Essentially, the supervisor's `start_child/1` takes the callback module, and
adds a childspec to the supervisor. This childspec then calls down into the
worker's `start_link/1` which takes the same callback module name as an
argument, and starts a gen_server using itself. Yes, it sounds complicated,
but it's not really.
