linux创建线程之pthread_create的具体使用

#include<stdio.h>
#include<stdlib.h>
#include<pthread.h>

/* 声明结构体 */
struct member
{
  int num;
  char *name;
};

/* 定义线程pthread */
static void * pthread(void *arg)
{
  struct member *temp;

  /* 线程pthread开始运行 */
  printf("pthread start!\n");

  /* 令主线程继续执行 */
  sleep(2);

  /* 打印传入参数 */
  temp = (struct member *)arg;
  printf("member->num:%d\n",temp->num);
  printf("member->name:%s\n",temp->name);

  return NULL;
}

/* main函数 */
int main(int agrc,char* argv[])
{
  pthread_t tidp;
  struct member *b;

  /* 为结构体变量b赋值 */
  b = (struct member *)malloc(sizeof(struct member));
  b->num=1;
  b->name="mlq";

  /* 创建线程pthread */
  if ((pthread_create(&tidp, NULL, pthread, (void*)b)) == -1)
  {
    printf("create error!\n");
    return 1;
  }

  /* 令线程pthread先运行 */
  sleep(1);

  /* 线程pthread睡眠2s，此时main可以先执行 */
  printf("mian continue!\n");

  /* 等待线程pthread释放 */
  if (pthread_join(tidp, NULL))
  {
    printf("thread is not exit...\n");
    return -2;
  }

  return 0;
}
