While read & write event of a fd is triggered in same loop of one
thread, the callbacks are called one by one.
I am forwarding data between 2 fds, just want to read from & write to
fd concurrently.

Is there a reason to use threads at all? Sounds unnecessary.
If you're doing TCP you might find this code helpful - it has a
write queue.

Hi
I am working for an packet forwarding tool. It opens 2 fds, reads
data from
one and sends to another.
It was implemented with single thread and uses only default ev_loop
and I
will write a multi-threaded version.
If I create 2 threads per fd, one for reading and another for
writing,
reader threads use libev ev_loop, and put any incoming data into
queue 1st
and 2nd,
the writer threads just wait for queues and write data to fds but
doesn't
use ev_loop to get EV_WRITE event,
is there any problem ?
Or should I create ev_loop for each writer thread and use
ev_async_send to
notify writers when queues get data?
Which mode is correct ?
thanks
