Request for remote command-line SSH server example

[Nicolas Lykke Iversen <nlykkei@xxxxxxxxx>]

Hi libssh-community!

I request a SSH server example for connecting with a client to obtain
remote command-line execution.

Is it necessary to request a PTY or is it enough to request a shell only?

Given that a PTY/shell is requested, how do I get a remote command-line?
Are their specific functions for executing the received commands? If so,
which?

I've tried following the tutorial (chapter 3), but it only shows code for a
SSH client requesting a PTY/shell.

Kind regards
Nicolas
