unlink vs remove in c++
提问by SyBer
What is the difference between remove and unlink functions in C++?
C++ 中的 remove 和 unlink 函数有什么区别？
回答by Kornel Kisielewicz
Apart from the fact that unlink is unix-specific (as pointed out by Chris), we read in the POSIX manual:
除了 unlink 是特定于 unix 的这一事实（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).
如果 path 未命名目录，则 remove(path) 等效于 unlink(path)。如果路径命名目录，remove(path) 等价于 rmdir(path)。
As for the directory-passed unlink, we read:
至于 directory-passed 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.
除非进程具有适当的权限并且实现支持在目录上使用 unlink()，否则路径参数不得命名目录。(...) 应用程序应使用 rmdir() 删除目录。

removeis portable, and unlinkis Unix-specific. :-P
remove是可移植的，并且unlink是特定于 Unix 的。:-P
回答by Quentin Perez
The remove()function removes the file or directory specified by path.
该remove()函数删除路径指定的文件或目录。
If path specifies a directory, remove(path)is the equivalent of
rmdir(path). Otherwise, it is the equivalent of unlink(path).
如果 path 指定目录，remove(path)则相当于
rmdir(path). 否则，它相当于unlink(path)。
From: man remove.
来自：man remove。
Good Luck ;)
祝你好运 ;）

unlink is not unix-specific, i don't know why people're saying that. see io.h. although you'll probably have to do something like
unlink 不是特定于 unix 的，我不知道人们为什么这么说。见io.h。虽然你可能不得不做类似的事情
#define unlink _unlink
