Having a daemon working absolutely fine with libevents - no problems
with the basic use case.
However for a somewhat more complex handler where I need to wait for
another event to happen _within_ an event handler - as that determines
how I return from that hanlder. I.e. the function I am calling returns
immediately - and I need to wait up to X seconds for another handler
to be called:
event_init();
register xxx handler on socket 1 with REST interface
register zzz handler on socket 2 which gets OK/NOK callbacks from
a backend system.
event_dispatch().
done.
xxx_handler() {
call a function which
ultimately causes a callback
wait for zzz_handler() to be called
with some timeout.
if (success)
... buf write OK
if (timeout)
... buff write timeout
else
... buff write errrr %x
}
zzz_hander() {
parse results
-> know success or fail
}
How is this best done ? Can I safely call event_loop (once) within an
event ?
Thanks,
Dw
