Masters, the younger brother is made a visual VS2015 + libssh2 login terminal tool, can now normal login on the terminal, but can't solve a problem, I use a libssh2_channel_exec () + libssh2_channel_read () function, can run a command at a time, but if there are any restart does not resolve, then restart need to reboot -f is it needed to enter y confirmation, then returns only the System will reboot! The Continue? [y/n] : unable to enter again restart y success, and I need to use the Vi command to change the file content, also can only identify the same problems behind the first article Vi command does not admit to input system, the trouble to explain each master, thank you!!!!!!
