Renaming a directory in C++

Im trying to rename a directory to the same name as an existing directory in a test in C++. I have tried SHFileOperation. This actually works mostly. The problem is that we have an auotmated test and for some reason during the automated test the test fails here. Works fine on a manual run but the automated not so much. We think it might be that some dialog box is popping up even though i have the flags set to not allow any. i also tried rename the C++ function. rename doesnt seem to work when trying to rename something to an existing name.

So is there any other method i could use?

You could try MoveFile which also work for directories. Though I doubt if any API is able to rename something to a name that already exists. https://msdn.microsoft.com/en-us/library/windows/desktop/aa365239(v=vs.85).aspx

I would definitely go for boost, but if you cannot use it, you must know that C++ does not have built-in support for such file operations.

The best you can do is use C's rename():

You could try boost::filesystem which has the advantage of portability if that's important to you.

namespace bfs=boost::filesystem;

std::string name("old_dir", "new_dir");

system::error_code ec = bfs::rename(name, new_name);

The ec is and error code object that can be referenced here so you could check for error conditions.
