need help to use libssh to archieve port forwarding

[赵长松]

 Hi,

I have written a ssh server program  based on libssh. It can achieve the basic 
functions of the server. Now I want to join ssh port forwarding in the 
program.But I do not know how to achieve the response of port forwarding 
requests.Will libssh support response port forwarding the request sent by the 
client?I would like to ask how to achieve and are there some similar examples?

Thanks
