libssh2_channel_close - close a channel

channel - active channel stream to set closed status on.

       Close  an  active data channel. In practice this means sending an SSH_MSG_CLOSE packet to the remote host
       which serves as instruction that no further data will be sent to it. The remote host may still send  data
       back until it sends its own close message in response. To wait for the remote end to close its connection
       as well, follow this command with libssh2_channel_wait_closed(3)

LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

       libssh2_channel_close - close a channel

       Return  0  on  success  or  negative  on failure. It returns LIBSSH2_ERROR_EAGAIN when it would otherwise
       block. While LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure per se.
