Linux中可用于删除文件的系统调用 [英] System calls in Linux that can be used to delete files

问题描述

在Linux上可以用来删除文件的系统调用是什么？我指的不是libc-wrapper使用的系统调用（依次由命令行工具使用）。

What are the system calls that can be used to delete a file on Linux? I am not referring to just the system calls used by the libc-wrapper(which in-turn are used by command line tools).

除了 unlink 和 unlinkat 可以用来删除Linux计算机上文件的系统调用是什么？

Other than unlink and unlinkat what are the system calls that could be used to delete files on a Linux machine?

推荐答案

rename（）和 renameat（）可以通过在文件上重命名另一个文件来删除文件。

rename() and renameat() can be used to delete a file by renaming another file over it.

如果您考虑将文件清空为删除的一种形式，则各种系统调用，包括 truncate（）和 open（）和 O_TRUNC 都可以

If you consider making a file empty to be a form of deletion, a variety of system calls, including truncate() and open() with O_TRUNC, can do that.
