Thanks for you reply.
The command did not exit, and I want it to be exit, so I close the channel to end the command. BTW, I also read stderr after stdout. The situation is the same.
Thanks

The command has already exited on the server, but the channel stays
open until all data has been read. "output nothing" is true for
stdout, but probably the program has output to stderr, which you
have to also read using libssh2_channel_read_stderr().
