connfd=%d\n", peeraddr.c_str(), channel->fd()); + } else { + printf("%s disconnected! connfd=%d\n", peeraddr.c_str(), channel->fd()); + } + }; + srv.onMessage = [](const SocketChannelPtr& channel, Buffer* buf) { + // echo + channel->write(buf); + }; + srv.setThreadNum(4); + srv.start(); + + // press Enter to stop + while (getchar() != '\n'); + return 0; +} +``` + +**注意**: + +以上示例只是简单的`echo`服务，TCP是流式协议，实际应用中请务必添加边界进行拆包。
+文本协议建议加上`\0`或者`\r\n`分隔符，可参考 [examples/jsonrpc](examples/jsonrpc);
+二进制协议建议加上自定义协议头，通过头部长度字段表明负载长度，可参考 [examples/protorpc](examples/protorpc);
+通过`setUnpack`（c接口即`hio_set_unpack`）设置拆包规则，支持固定包长、分隔符、头部长度字段三种常见的拆包方式，
+内部根据拆包规则处理粘包与分包，保证`onMessage`回调上来的是完整的一包数据，大大节省了上层处理粘包与分包的成本。
+不想自定义协议和拆包组包的可直接使用现成的`HTTP/WebSocket`协议。
+
+`channel->write`（c接口即`hio_write`）是非阻塞的（事件循环异步编程里所有的一切都要求是非阻塞的），且多线程安全的。
+发送大数据时应该做流控，通过`onWriteComplete`监听写完成事件，在可写时再发送下一帧数据。
+具体示例代码可参考 [examples/tinyhttpd.c](examples/tinyhttpd.c) 中的 `http_serve_file`。
+
+`channel->close`（c接口即`hio_close`) 也是多线程安全的，这可以让网络IO事件循环线程里接收数据、拆包组包、反序列化后放入队列，
+消费者线程/线程池从队列里取出数据、处理后发送响应和关闭连接，变得更加简单。

+如使用`server.start()`内部会另起线程运行，不会阻塞当前线程，但需要注意`router`和`server`的生命周期，
+不要定义为局部变量被析构了，可定义为类成员变量或者全局变量，下面的`WebSocket`服务同理。

It is fast and scalable, and it closely resembles the API +and behavior of Linux' epoll. + +## Rationale + +Unlike Linux, OS X, and many other operating systems, Windows doesn't +have a good API for receiving socket state notifications. It only +supports the `select` and `WSAPoll` APIs, but they +[don't scale][select scale] and suffer from +[other issues][wsapoll broken]. + +Using I/O completion ports isn't always practical when software is +designed to be cross-platform. Wepoll offers an alternative that is +much closer to a drop-in replacement for software that was designed +to run on Linux. + +## Features + +* Can poll 100000s of sockets efficiently. +* Fully thread-safe. +* Multiple threads can poll the same epoll port. +* Sockets can be added to multiple epoll sets. +* All epoll events (`EPOLLIN`, `EPOLLOUT`, `EPOLLPRI`, `EPOLLRDHUP`) + are supported. +* Level-triggered and one-shot (`EPOLLONESTHOT`) modes are supported +* Trivial to embed: you need [only two files][dist]. + +## Limitations + +* Only works with sockets. +* Edge-triggered (`EPOLLET`) mode isn't supported. + +## How to use + +The library is [distributed][dist] as a single source file +([wepoll.c][wepoll.c]) and a single header file ([wepoll.h][wepoll.h]).
+Compile the .c file as part of your project, and include the header wherever +needed. + +## Compatibility + +* Requires Windows Vista or higher. +* Can be compiled with recent versions of MSVC, Clang, and GCC. + +## API + +### General remarks + +* The epoll port is a `HANDLE`, not a file descriptor. +* All functions set both `errno` and `GetLastError()` on failure. +* For more extensive documentation, see the [epoll(7) man page][man epoll], + and the per-function man pages that are linked below. + +### epoll_create/epoll_create1 + +```c +HANDLE epoll_create(int size); +HANDLE epoll_create1(int flags); +``` + +* Create a new epoll instance (port). +* `size` is ignored but most be greater than zero. +* `flags` must be zero as there are no supported flags. +* Returns `NULL` on failure. +* [Linux man page][man epoll_create] + +### epoll_close + +```c +int epoll_close(HANDLE ephnd); +``` + +* Close an epoll port. +* Do not attempt to close the epoll port with `close()`, + `CloseHandle()` or `closesocket()`. + +### epoll_ctl + +```c +int epoll_ctl(HANDLE ephnd, + int op, + SOCKET sock, + struct epoll_event* event); +``` + +* Control which socket events are monitored by an epoll port. +* `ephnd` must be a HANDLE created by + [`epoll_create()`](#epoll_createepoll_create1) or + [`epoll_create1()`](#epoll_createepoll_create1). +* `op` must be one of `EPOLL_CTL_ADD`, `EPOLL_CTL_MOD`, `EPOLL_CTL_DEL`. +* `sock` must be a valid socket created by [`socket()`][msdn socket], + [`WSASocket()`][msdn wsasocket], or [`accept()`][msdn accept]. +* `event` should be a pointer to a [`struct epoll_event`](#struct-epoll_event).
+ If `op` is `EPOLL_CTL_DEL` then the `event` parameter is ignored, and it + may be `NULL`. +* Returns 0 on success, -1 on failure. +* It is recommended to always explicitly remove a socket from its epoll + set using `EPOLL_CTL_DEL` *before* closing it.
+ As on Linux, closed sockets are automatically removed from the epoll set, but + wepoll may not be able to detect that a socket was closed until the next call + to [`epoll_wait()`](#epoll_wait). +* [Linux man page][man epoll_ctl] + +### epoll_wait + +```c +int epoll_wait(HANDLE ephnd, + struct epoll_event* events, + int maxevents, + int timeout); +``` + +* Receive socket events from an epoll port. +* `events` should point to a caller-allocated array of + [`epoll_event`](#struct-epoll_event) structs, which will receive the + reported events. +* `maxevents` is the maximum number of events that will be written to the + `events` array, and must be greater than zero. +* `timeout` specifies whether to block when no events are immediately available. + - `<0` block indefinitely + - `0` report any events that are already waiting, but don't block + - `≥1` block for at most N milliseconds +* Return value: + - `-1` an error occurred + - `0` timed out without any events to report + - `≥1` the number of events stored in the `events` buffer +* [Linux man page][man epoll_wait] + +### struct epoll_event + +```c +typedef union epoll_data { + void* ptr; + int fd; + uint32_t u32; + uint64_t u64; + SOCKET sock; /* Windows specific */ + HANDLE hnd; /* Windows specific */ +} epoll_data_t; +``` + +```c +struct epoll_event { + uint32_t events; /* Epoll events and flags */ + epoll_data_t data; /* User data variable */ +}; +``` + +* The `events` field is a bit mask containing the events being + monitored/reported, and optional flags.
