如何将参数传递给 boost::thread? [英] How to pass an argument to boost::thread?

问题描述

thread_ = boost::thread( boost::function< void (void)>( boost::bind( &clientTCP::run , this ) ) );  

run 是否可能有这样的参数:

is it possible that run has an argument like this :

void clientTCP::run(boost:function<void(std::string)> func);

如果是，我的 boost::thread 调用应该如何编写

and if yes how my boost::thread call should be written

谢谢.

推荐答案

下面的代码boost::bind( &clientTCP::run , this ) 定义了一个函数回调.它在当前实例(this)上调用函数run.使用 boost::bind，您可以执行以下操作:

The following code boost::bind( &clientTCP::run , this ) defines a function callback. It calls the function run on the current instance (this). With boost::bind you can do the following:

// Pass pMyParameter through to the run() function
boost::bind(&clientTCP::run, this, pMyParameter)

请参阅此处的文档和示例:

See the documentation and example here:

如果你想构造一个实例带有函数的 boost::thread 或需要的可调用对象要提供的参数，这可以是通过传递额外的参数来完成到 boost::thread 构造函数:

If you wish to construct an instance of boost::thread with a function or callable object that requires arguments to be supplied, this can be done by passing additional arguments to the boost::thread constructor:

void find_the_question(int the_answer);

boost::thread deep_thought_2(find_the_question,42);
