[libuv] What are the differents between Windows and Linux server in libuv.

[ssrlivebox]

I have write a server / client for Shadowsocks(R) protocol based on libuv.

It's looks fine in windows server. but it's weird in linux.


I try to fix this issue for a few days and can not resolve it.


This is the invalid code I 
added.  
https://github.com/ShadowsocksR-Live/shadowsocksr-native/blob/master/src/client/tunnel.c#L88


My project site is 
ShadowsocksR-Native https://github.com/ShadowsocksR-Live/shadowsocksr-native


Please help me, any suggestions are welcome.


code snippet.

#if defined(_WIN32)
    return (int) handle->socket;
#elif defined(__APPLE__)
    int uv___stream_fd(const uv_stream_t* handle);

        flags = 0;
    }
    return fcntl(fd, F_SETFL, flags | O_NONBLOCK);
#else
    return 0;
#endif
}

    int opt = enable ? 1 : 0;
    setsockopt(fd, SOL_TCP, TCP_NODELAY, (char *)&opt, sizeof(opt));
