c++ - 在 C++ 中取消链接与删除

Question

C++ 中的 remove 和 unlink 函数有什么区别？

Answer 1

除了 unlink 是特定于 unix 的(正如 Chris 所指出的)，我们在 POSIX 手册中读到:

If path does not name a directory, remove(path) is equivalent to unlink(path). If path names a directory, remove(path) is equivalent to rmdir(path).

对于目录传递的unlink，我们读到:

The path argument must not name a directory unless the process has appropriate privileges and the implementation supports using unlink() on directories. (...) Applications should use rmdir() to remove a directory.
