(1)std::thread线程函数中可以直接改变类的成员变量,但是不是立马就可以改变,如果主线程过快退出,会造成类的成员变量无法改变的假象。这样你就入坑了,怎么也找不到变量为啥是0的原因。
std::thread *t1 = new std::thread((&test_mutex)); threadlist.push_back(t1); } for(std::list<std::thread*>::const_iterator i = threadlist.begin(); i != threadlist.end(); i++ ) { (*i)->join(); } clock_t finish = clock(); printf("result:%d\n", total1); printf("c...

因为thread和mutex是C++11才引入的,所以一开始考虑的是不是CMakeList上没有加编译选项,于是加上set(CMAKE_CXX_FLAGS$ {CMAKE_CXX_FLAGS} -std = c ++ 11)经过一番尝试,发现并无效果。 后来受到博客CLion安装mingw并配置以支持c++11多线程编程的启发,重新安装mingw编译器,但是不成功。 又看到博客mingw-w64安...

下面示例代码中,使用了std::vector<std::thread>来存储线程对象,在每个客户端连接时创建一个新线程来处理该连接。使用多线程可以让服务器同时处理多个客户端连接,提高并发性能。 #include <iostream>#include <winsock2.h>#include <ws2tcpip.h>#include <thread>#include <vector>#pragma comment(lib, "ws2_32....
When a thread is about to start waiting on a condition variable, it increments the counter and suspends itself using the global keyed event, passing the address of the condition variable as the key. Another thread may read the counter to tell how many threads that it will have to wake up...
