4807 | * term_out() always completely empties inbuf. Therefore, |
4808 | * there's no reason at all to return anything other than zero |
4809 | * from this function, because there _can't_ be a question of |
4810 | * the remote side needing to wait until term_out() has cleared |
4811 | * a backlog. |

4813 | * This is a slightly suboptimal way to deal with SSH2 - in |
4814 | * principle, the window mechanism would allow us to continue |
4815 | * to accept data on forwarded ports and X connections even |
4816 | * while the terminal processing was going slowly - but we |
4817 | * can't do the 100% right thing without moving the terminal |
4818 | * processing into a separate thread, and that might hurt |
4819 | * portability. So we manage stdout buffering the old SSH1 way: |
4820 | * if the terminal processing goes slowly, the whole SSH |
4821 | * connection stops accepting data until it's ready. |
