using是C++11加入的,它叫做_alias declaration_(别名声明)。...MyClassFunc = void(MyClass::*)(double, std::string) 除此之外,using能更方便的为模板取别名(alias templates),这是typedef...初学者选择typename可能会对模板有更好的了解(毕竟若模板传进来的是int,它是内
#include <thread> #include <vector> #include <iostream> int main() { // Create a vector of threads std::vector<std::thread> vecOfThreads; // Create a function object std::function<void()> func = []() { //Do Some Important Work // ... //Print Thread ID std::cout << "Fro...
CommonFunc 函数使用 TlsGetValue 函数访问与调用线程本地索引关联的数据。 在每个线程终止之前,它会释放其动态内存。 在进程终止之前,它会调用 TlsFree 来释放索引。 C++ 复制 #include <windows.h> #include <stdio.h> #define THREADCOUNT 4 DWORD dwTlsIndex; VOID ErrorExit (LPCSTR message); VOID Common...

To handle an event, you overload an event handler function, like so:c++ 複製 struct my_btn : button { void on_char(ev::char& e); }; Here you respond to the character pressed event, or, for you Win32 API lovers, the WM_CHAR message....
This section shows the use of a DLL entry-point function to set up a thread local storage (TLS) index to provide private storage for each thread of a multithreaded process.
