Specs
Called after an application has been stopped.
This function is called after an application has been stopped, i.e., after its
supervision tree has been stopped. It should do the opposite of what the
start/2
callback did, and should perform any necessary cleanup. The return
value of this callback is ignored.
state
is the state returned by start/2
, if it did, or []
otherwise.
If the optional callback prep_stop/1
is present, state
is its return
value instead.
use Application
defines a default implementation of this function which does
nothing and just returns :ok
.
