Linux辅导：liunx中多线程操作实例解析

会计考友 · 发表于 2012-8-4 12:07:07

自己写的一个小轨范，用来实现liunx中多线程程的挪用。例子清楚易懂
/*
该函数实现了线程的挪用，多线程的用法

void *thread_function(void *arg);
void *thread_function1(void *arg);
char message = "Hello World";

int main() {
int res;
pthread_t a_thread;
void *thread_result;
int thread_num1=0;
int thread_num2=1;
//第一个线程
res = pthread_create(&a_thread, NULL, thread_function, (void *)thread_num1);
if (res != 0) {
perror("Thread creation failed");
