libuv - 我在哪里可以找到关于 uv_poll_init 的文档？

Question

我正在查看https://github.com/benfleis/samples/blob/master/libuv/stdio/stdio_poll.c上的 libuv 示例并试图理解它。

我基本上理解它，但我在底部的 uv_poll_init 遇到了一些问题，我找不到任何文档。

有人可以指点我一些关于它的文件吗？

谢谢！

官方文档在include/uv.h头文件中以注释的形式出现，其中提供了以下文档uv_poll_init()：

使用文件描述符初始化轮询观察程序。

但是，可以在此处找到一些涵盖观察者概念的更好的文档。简而言之：

uv_poll_init(loop, &stdin_watcher, STDIN_FILENO);

初始化stdin_watcher观察STDIN_FILENO。当 watcher 启动时，它的所有回调都将在loop.

这是程序的基本伪流程：

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)
