[erlang-questions] gen module documentation availability
Fri Dec 26 10:44:23 CET 2008
The gen module is not documented because it is not an official API.
The gen module is an implementation which happens to be shared by
gen_server, gen_event and gen_fsm.
The interface towards the gen module might be changed at anytime while
at the same time
the API's towards gen_server, gen_event and gen_fsm will remain
untouched or backwards compatible.
The gen module might even be removed or split into several modules.
The principle we have is that what's documented is the official API's
that will be kept stable and compatible.
I still think there is a minor risk for you in reusing the gen module
we have no immediate plans to
change it. And you can always copy the entire contents of the gen
module into your implementation if you want to be on the safe side.
