在UNIX下使用C ++删除文件 [英] Remove file in C++ under UNIX

问题描述

你们通常如何在Linux OS上删除文件?我正在考虑使用unlink函数调用，但是我想知道您是否有更好的主意，因为C ++标准没有提及文件删除操作，并且它取决于系统.

How do you guys typically delete files on Linux OS? I am thinking of using the unlink function call, but I wonder if you have a better idea, as the C++ standard has no mention of file deletion operation and it is system dependent.

推荐答案

是的-C ++标准将这些内容留给操作系统使用，因此，如果您使用的是Linux(或任何POSIX系统)，则

Yep -- the C++ standard leaves this stuff up to the OS, so if you're on Linux (or any POSIX system), unlink() is what you've got.

C标准提供了 remove() ，您可以尝试，但请记住，其，因此它并不能真正阻止您进入特定于平台的文件系统详细信息(链接等).

The C standard provides remove(), which you could try, but keep in mind that its behavior is unspecified for anything other than a 'regular file', so it doesn't really shield you from getting into platform-specific filesystem details (links, etc).
