线程初级基础（一）
一，单线程例子
#include <stdio.h>#include <string.h>#include <iostream>#include <pthread.h>using namespace std;void *thread_func(void *arg){ for(int i=0; i<3; i++) { sleep(1); cout<<"Running in thread"<<endl; } return NULL;}int main(){ pthread_t tid1; if(pthread_create(&tid1, NULL, thread_func, NULL) != 0) { cout<<"thread create error"<<endl; return -1; } for(int i=0; i<3; i++) { cout<<"Running in main process"<<endl; sleep(1); } pthread_join(tid1, NULL); return 0;}
输出结果：
[root@localhost thread]# ./a.out Running in main processRunning in main processRunning in threadRunning in threadRunning in main processRunning in thread[root@localhost thread]# ./a.out Running in main processRunning in threadRunning in main processRunning in threadRunning in main processRunning in thread[root@localhost thread]# ./a.out Running in main processRunning in threadRunning in main processRunning in main processRunning in threadRunning in thread
