gen_event and multiple handler ``instances''
Mon May 3 23:11:46 CEST 2004
I'm making my away around the OTP modules (it seems that I need just
about every one of them for a simple application I'm writing) and I've
got a question regarding gen_event.
It seems that gen_event doesn't want you to have multiple handlers
from the same module registered. I was hoping for something more like
NSNotificationCenter (if you're familiar with Objective C) where I
could register something more like a process. Does something exist
that is more suited to my needs?
Essentially, my app consists of a multicast listener that watches for
environmental data updates on my network and transforms those into
events. I have another process that is a TCP listener that accepts
connections and sends the updates across it, essentially transforming
the local multicast to TCP unicast. I thought I could get away with
error_logger:info_msg("Starting event handler with: ~p~n",
This does seem to do what I want, but it's unclear to me how I'd go
about deleting the handler when the socket disconnects:
Currently, I just let the handler crash and get a giant error message,
but it seems like there would be a better way. Any ideas?
