[libssh2] How to check that written bytes have been forwarded to remote port?

Hello,
How can I check the status of a forwarded channel?

I am forwarding a channel from local port to a remote MySQL server.
I have to identify the condition where I have setup a connection to MySQL
successfully.
And then the MySQL server goes off.

Then If I am writing into the forwarded channel it still writes
successfully.
(Returns the number of bytes written).

But as I have to set the channel a non blocking one,
read also simply returns LIBSSH2_ERROR_EAGAIN.

How can I identify that the written bytes on the channel had not been
forwarded to MySQL port?
