哪裏可以找到有關uv_poll_init的文檔？

Question

我在看0123u的libuv示例並試圖理解它。

我大部分都明白這一點，但我在uv_poll_init的底部遇到了一些麻煩，而且我找不到任何文檔。

有人可以指向我的一些文件嗎？

謝謝！

Answer 1

的正式文檔是在include/uv.h頭文件的註釋的形式，其提供了以下文檔uv_poll_init()：

初始化使用文件描述符輪詢觀察者。

但是，一些涵蓋觀察者概念的更好的文檔可以在here找到。總之：

uv_poll_init(loop, &stdin_watcher, STDIN_FILENO); 

初始化stdin_watcher觀察STDIN_FILENO。觀察者啓動時，其所有回調將在loop的範圍內調用。

這裏是程序的基本僞流程：

stdout_cb: 
    write whatever is in log_buf to stdout 
    stop listening for when I can write to stdout 

log: 
    write message to log_buf 
    have stdout_watcher listen for when its file becomes writeable 
    when it becomes writable, stdout_cb will be called 

stdint_cb: 
    read from stdin 
    call log 

set_non_blocking: 
    set file descriptor as non-blocking 

main: 
    set stdin/out to nonblocking 

    get handle to default event loop 
    initialize stdint_watcher, it will listen to stdin and its callback will 
    run within the default loop 
    initialize stdout_watcher, it will listen to stdout and its callback will 
    run within the default loop 
    have stdin_watcher listen for when its file becomes readable 
    when it becomes readable, stdin_cb will be called 
    run the event loop until no more work exists 
    in this case, when both watchers are not running (i.e. stopped)
