In the attached archive an example based on libssh2 docs:
http://www.libssh2.org/examples/tcpip-forward.html
In the attached code the port forwarding is implemented. In the infinity
loop we preforms port forwarding of the PostgreSQL port on the remote
computer. In the end of the loop all resources are freeing.
But memory increases constantly.
I think that I'm doing something wrong. Tell me please what exactly? )
