I use tshark through an openssl tunnel.

If the tunnel closes, tshark goes on.

This is due to the fact, when writing to a pipe, it flushes the output, but the
result of the flush is ignored.

Therefore, it goes on capturing, fwrite is successful (in the FILE buffer), and
flush fails.

Two ways to correct that :
 taking care of SIGPIPE (now it is SIG_IGNed)
 taking care of the error generated by fflush in the different library
functions.

Thanks,

Pierre JUHEN
