C++ 线程传递多个参数

使用多线程处理共享数据  有些情况下需要传递多个参数

定义一个结构体：将这个结构体指针，作为void *形参的实际参数传递. 

函数中需要定义一个mypara类型的结构指针来引用这个参数

struct thread_param

{

  void * pthis = NULL;

  int i = -1;

};

int main() { 　　 vector<pthread_t> thread_ids(1); for (size_t i = 0; i < 1; ++i) { struct thread_param tp; tp.pthis = (void *)this; tp.i = i; if (0 != pthread_create(&thread_ids[i], NULL, &do_check_thread_func, (void *)&tp)) { WRITE_LOG(LOG_ERROR, "pthread_create failed in 10018877"); return -1; } WRITE_LOG(LOG_DEBUG, "do_check_thread_func create thread successfully, tid: %u", thread_ids[i]); } for (size_t i = 0; i < 1; ++i) { pthread_join(thread_ids[i], NULL); } return 0; } void* do_check_thread_func(void *data) { thread_param *tt; tt = (struct thread_param*)data; void *param = tt->pthis; int i = tt->i; myclass* pThis = (myclass*)param; WRITE_LOG(LOG_DEBUG, "10018877 do_check_thread_func create thread successfully, i:%d", i); }
