That does indeed work - I think I want 'permanent' so<br>
that the worker comes back if the application crashes - is it as<br>
simple as that?<br>
<br>
My question about ChildSpec is about 'Module' and the erlang docs.<br>
<br>
>From the erlang docs:<br>
"Modules is used by the release handler during code replacement to<br>
determine which processes are using a certain module. As a rule of<br>
thumb Modules should be a list with one element [Module], where Module<br>
is the callback module, if the child process is a supervisor,<br>
gen_server or gen_fsm."<br>
<br>
My 'sender_worker' is just a module - it is not a supervisor,<br>
gen_server or gen_fsm. Is there some specific interface that the<br>
module function 'boot_send' needs to conform to - or is returning {ok,<br>
Pid} what it needs to do?<br>
