[zeromq-dev] gist: using signalfd with zloop - synchronous signal delivery

[Michael Haberler]

since it's a bit tricky (or rather I didnt get it right first time..):

here is an example for using signalfd(2) for synchronous signal delivery in a zloop reactor

the key steps are:
- disable czmq signal handling by zsys_handler_set() once the context is created; this will also disable setting of zctx_interrupted
- block all signals from being handled via traditional handlers
- explicitly enable signals you want delivered via signalfd()
