Issue with reading data on socket

[sai koushik]

Hi ,

      I tried to add loop still no success.
added :
       ev_loop(EV_A_ 0);

is it possible to read data asynchronously on socket using any type of
watcher functions .

can u point me some socket client examples in libev, i
checked libev-examples module in git but it is not matching for my use-case.

Thanks,
Sai.
