[c++] thread 기본 구조, 모양

1. 

thread에 함수 넣는 부분에 &를 붇이지 않아도 함수 이름이 갖고 있는 해당 메모리 주소로 인식된다는 말을 듣고 해보았지만 에러가 떠서 이것 저것 찾다가 그냥 예시를 찾았다.

2.

#include <cstdio> #include <string> #include <iostream> #include <pthread.h> void* print(void* data) {     std::cout << *((std::string*)data) << "\n";     return NULL; // We could return data here if we wanted to } int main() {     std::string message = "Hello, pthreads!";     pthread_t threadHandle;     pthread_create(&threadHandle, NULL, &print, &message);     // Wait for the thread to finish, then exit     pthread_join(threadHandle, NULL);     return 0; } A better alternative, if you're able to, is to use the new C++11 thread library. It's a simpler, RAII interface that uses templates so that you can pass any function to a thread, including class member functions (see this thread). Then, the above exmaple simplifies to this: #include <cstdio> #include <string> #include <iostream> #include <thread> void print(std::string message) {     std::cout << message << "\n"; } int main() {     std::string message = "Hello, C++11 threads!";     std::thread t(&print, message);     t.join();     return 0;  }
