【问题描述】：

我正在尝试设置会话设置，但遇到了一个我不太明白的错误，我能够正确设置会话设置，根据 Libtorrent 文档，我只需将 session_settings 结构传递给 set_settings 一次我更改了任何值。

using namespace libtorrent;
session* Session;
session_status* Session_Status;
session_settings* Session_Settings;

bool Start_Client_Sess()

    Session = new session;
    Session_Status = new session_status;
    Session_Settings = new session_settings;
    Session->settings( );

    std::cout << "upload_rate_limit " << Session_Settings->upload_rate_limit << " \n";
    std::cout << "dht_announce_interval " << Session_Settings->dht_announce_interval << " \n";

    Session_Settings->upload_rate_limit = 200;
    Session_Settings->dht_announce_interval = 1800;

    Session->set_settings( Session_Settings ); // error

错误：

1>Source\Client_F.cpp(66): error C2664: 'void libtorrent::session::set_settings(const libtorrent::session_settings &)' : cannot convert argument 1 from 'libtorrent::session_settings *' to 'const libtorrent::session_settings &'
1>          Reason: cannot convert from 'libtorrent::session_settings *' to 'const libtorrent::session_settings'
1>          No constructor could take the source type, or constructor overload resolution was ambiguous

【参考方案1】：

正如错误消息所说，您不必将指针传递给此函数。

Session->set_settings( *Session_Settings );

【讨论】：

事实上，一个更好的解决方案是简单地不在堆上分配 Session_Settings 或 Session_Status。
