介绍Linux下多线程编程的博客：https://www.cnblogs.com/nfcm/p/7653433.html
pthread_create传递带参数的函数：https://blog.csdn.net/computerme/article/details/52421928
结合这些知识，自己写了了一个demo，其中实现了多线程、传递参数与利用锁进行同步。
#include <stdio.h> #include <pthread.h> #include <unistd.h> #include <stdlib.h> #define thread_num 8 int num=0; pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER; typedef struct String{ char c[20]; int len; } Str; void * func_thread(void * arg) { Str * para=(Str *)arg; pthread_mutex_lock(&mutex); while(num<20){ printf("this is func_%s,%d!\n",para->c,para->len); num++; pthread_mutex_unlock(&mutex); sleep(1); pthread_mutex_lock(&mutex); } pthread_mutex_unlock(&mutex); } int func() { pthread_t pid[thread_num]; void * ps[thread_num]; Str arg[8]={{"zero",4},{"one",3},{"two",3},{"three",5},{"four",4}, {"five",4},{"six",3},{"seven",5}}; int i; for(i=0;i<thread_num;i++) if(pthread_create(pid+i, NULL, func_thread,arg+i)) return -1; for(i=0;i<thread_num;i++) pthread_join(pid[i],ps+i); printf("%d\n",num); return 0; } int main() { func(); return 0; } //gcc prac1.c -o prac1 -lpthread我是在gcc下编译的：gcc demo.c -o demo -lpthread
