问题描述
如果我使用 malloc
在我的 C 程序中分配了内存,现在我想退出,我是否必须释放分配的内存,或者我可以假设因为我的整个程序终止,它将是被操作系统释放?
If I allocated memory in my C program using malloc
and now I want to exit, do I have to free the allocated memory, or can I assume that since my entire program terminates, it will be freed by the OS?
我在 Linux 环境中运行.
I run in Linux environment.
推荐答案
任何现代操作系统都会在进程终止后清理所有内容,但依赖于此通常不是一个好的做法.
Any modern operating system will clean up everything after a process terminates, but it's generally not a good practice to rely on this.
这取决于您正在编写的程序.如果它只是一个快速运行和终止的命令行工具,您可能不会费心清理.但请注意,正是这种心态导致守护进程和长时间运行的程序出现内存泄漏.
It depends on the program you are writing. If it's just a command line tool that runs and terminates quickly, you may not bother cleaning up. But be aware that it is this mindset that causes memory leaks in daemons and long-running programs.
