Re: session establishment struck

[Vasuki Gubbi <gkvasuki@xxxxxxxxx>]

Aris,

Thank you for your reply. But in the current case, session has not been
established as it is struck at user authentication, so problem might not be
multithreaded corruption of the data structures. Read and write threads are
created after establishing the session.

But you raise a very important issue. In our case, we have a third party
library that parses the reads from the network and also writes data to the
network. Library expects read and write function handler to be registered,
with the expectation that user implemented read blocks till the data is
available from the network to parse the data. Write method is called by the
library once a data is formatted to write to the network. Third party
library is the one that creates separate threads for reading and writing
once we create a network connection.
In such a case, can you please let me know how I can use libssh?

Regards,
Vasuki
