Apart from the fact that unlink is unix-specific (as pointed out by Chris), we read in the POSIX manual:
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).
As for the directory-passed unlink, we read:
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.

除了 unlink 是特定于 UNIX 的事实（正如 Chris 所指出的）之外，我们在 POSIX 手册中读到：
至于目录传递的
unlink，我们读到：Apart from the fact that unlink is unix-specific (as pointed out by Chris), we read in the POSIX manual:

unlink, we read:remove是可移植的，而unlink是 Unix 特定的。 :-Premoveis portable, andunlinkis Unix-specific. :-Premove()函数删除路径指定的文件或目录。如果path指定一个目录，
remove(path)相当于rmdir(路径)。否则，它相当于unlink(path)。来自：

The
remove()function removes the file or directory specified by path.If path specifies a directory,
remove(path)is the equivalent ofrmdir(path). Otherwise, it is the equivalent ofunlink(path).From:

unlink 不是特定于 UNIX 的，我不知道为什么人们这么说。参见 io.h。尽管您可能需要执行类似

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

remove()是 C++ 标准 (N4860 29.11.14.30) 的一部分。unlink()不是。remove()is part of the C++ standard (N4860 29.11.14.30).unlink()is not.
