Boost thread 教程

#include <boost/thread.hpp>
#include <iostream>
#include <stdio.h>

class SpecificWork {
private:
	int p_;
public:
	SpecificWork(int value) : p_(value) { }

	void operator()() {
		printf("Value is %d\n", p_);
	}
};

int main() {
	int i = 1;
	SpecificWork work(i);
	boost::thread worker(work);

	worker.join();

}

启动函数对象线程，注意， work(i) i可以是常数也可以是变量，但是假如写成

boost::thread worker(SpecificWork(1)); 就只能是常数了。

 

而对于函数来说， 就没有上述限制

void hello(int value) {
	printf("hello %d\n", value);
}

int main() {
	int i = 1;
	SpecificWork work(i);
	boost::thread worker(&hello, i);//ok
	boost::thread worker(&hello, 1);//ok
	worker.join();

}

 

另外，可以用 boost::bind 绑定函数

int main() {
	int i = 1;
	SpecificWork work(i);
	//boost::thread worker(&hello, i); //ok
	boost::thread worker(boost::bind(&hello, i)); //ok
	boost::thread worker(boost::bind(&hello, 1)); //ok
	worker.join();
}

 

bind 的用法还不是很熟，待填
