在C程序中查找内存泄漏的最佳方法 [英] Best way to find memory leaks in a C program

问题描述

我正在尝试完成大学作业，并且评分标准指定了5％的内存管理-特别是对于没有内存泄漏的情况.

I am trying to complete a college assignment, and the marking criteria specifies 5% for memory management - specifically for having no memory leaks.

据我了解，简单C程序中的内存泄漏仅是由已被程序放弃的指针引起的，即，从未具有相应free的malloc/calloc/etc调用.

As I understand it, memory leaks in simple C programs, are only caused by pointers which have become abandoned by the program - ie, malloc/calloc/etc calls which are never have a corresponding free.

我的问题分为三个部分:

My question is in 3 parts:

1. 在Solaris上最简单的方法是什么 和OSX来证明"您还没有 泄漏了任何内存?
2. XCode是否具有 任何有助于确定记忆的工具 泄漏?
3. 执行操作系统 释放所有先前分配的 一旦在C程序中的内存 程序结束了吗?

1. Whats the simplest way on Solaris and OSX to 'prove' that you haven't leaked any memory?
2. Does XCode have any tools to help determine memory leaks?
3. Does the operating system release all previously allocated memory within a c program once the process ends?

推荐答案

Valgrind 是你的朋友.
