libssh (C++): Possible to redirect some output from some given `fd` to an `ssh_channel` on remote side?

Question

Using the libssh library, one can communicate with a remote host by opening a channel:

// Assume authentication for sshSession has been completed
ssh_channel channel_to_remote = ssh_channel_new(sshSession);
ssh_channel_open_session(channel_to_remote)

Does this channel happen to have a file descriptor that I can access on the remote side? If I have a file descriptor that is already open on my local side, is it possible to use the channel to notify the remote host about the file descriptor?

I have a ready-made executable that I wish to run on the remote side, and this executable writes output to a specific file descriptor (let us call it fd 3). Is it possible to redirect this output from fd 3 to the channel?

Cheers in advance!

Use a combination of dup() and ssh_channel_callbacks_struct .
