スレッド処理

Last updated at Posted at 2024-09-25

スレッド処理

th1とth2のスレッドを作成し、実行する。
コンパイルの時に-pthreadを付けて実行すること。

#include <stdio.h>
#include <iostream>
#include <thread>

void ThreadFunc(int num) {
  std::cout << "ThreadFunc " << num << std::endl;
}

int main() {
  std::thread th1(ThreadFunc, 1);
  
  auto func = [](std::string msg) {
    std::cout << "thread message : " << msg << std::endl;
  };

  std::thread th2(func, "Hello, World!");
  std::cout << "th2 id : " << th2.get_id() << std::endl;

  th1.join();
  th2.join();

  return 0;
}

実行結果

th2 id : 140081530832448
thread message : Hellow, World!
ThreadFunc 1

備忘録

-pthreadでコメント来ていたので、備忘録
昔のことを忘れず、発生した時のために対応するメモ書き
現場によっては環境が古いなんてざらにある
