多参数函数通过在pthread

本文介绍了多参数函数通过在pthread_create（）调用？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我需要多个参数传递给我想一个单独的线程调用一个函数。我阅读，要做到这一点的典型方式是定义一个结构，一个指针传递的功能这一点，解引用它的参数。但是，我无法得到这个工作：

I need to pass multiple arguments to a function that I would like to call on a separate thread. I've read that the typical way to do this is to define a struct, pass the function a pointer to that, and dereference it for the arguments. However, I am unable to get this to work:

#include <stdio.h> #include <pthread.h> struct arg_struct { int arg1; int arg2; }; void *print_the_arguments(void *arguments) { struct arg_struct *args = (struct arg_struct *)args; printf("%d\n", args -> arg1); printf("%d\n", args -> arg2); pthread_exit(NULL); return NULL; } int main() { pthread_t some_thread; struct arg_struct args; args.arg1 = 5; args.arg2 = 7; if (pthread_create(&some_thread, NULL, &print_the_arguments, (void *)&args) != 0) { printf("Uh-oh!\n"); return -1; } return pthread_join(some_thread, NULL); /* Wait until thread is finished */ }

这个输出应该是：

The output for this should be:

5 7

但是当我运行它，我实际上得到：

But when I run it I actually get:

141921115 -1947974263

任何人都知道我在做什么错了？

Anyone know what I'm doing wrong?

推荐答案

由于你说

结构arg_struct * ARGS =（结构arg_struct *）ARGS;

而不是

结构arg_struct * ARGS =参数;
