WIN32_FIND_DATA - Get the absolute path

Question

I am using something like this:

std::string tempDirectory = "./test/*"; WIN32_FIND_DATA directoryHandle; memset(&directoryHandle, 0, sizeof(WIN32_FIND_DATA));//perhaps redundant??? std::wstring wideString = std::wstring(tempDirectory.begin(), tempDirectory.end()); LPCWSTR directoryPath = wideString.c_str(); //iterate over all files HANDLE handle = FindFirstFile(directoryPath, &directoryHandle); while(INVALID_HANDLE_VALUE != handle) { //skip non-files if (!(directoryHandle.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)) { //convert from WCHAR to std::string size_t size = wcslen(directoryHandle.cFileName); char * buffer = new char [2 * size + 2]; wcstombs(buffer, directoryHandle.cFileName, 2 * size + 2); std::string file(buffer); delete [] buffer; std::cout << file; } if(FALSE == FindNextFile(handle, &directoryHandle)) break; } //close the handle FindClose(handle); 

which prints the names of each file in the relative ./test/* directory.

Is there a way to determine the absolute path of this directory, just as realpath() does on Linux without involving any third-party libraries like BOOST? I would like to print the absolute path to each file.

Answer 1

See the GetFullPathName function.

Answer 2

You can try GetFullPathName

Or you can use SetCurrentDirectory and GetCurrentDirectory . You can save the current directory before doing this, so you can return to it later.

In both cases, you only need to get the full path to your search directory. The API call is slow. Inside the loop, you simply concatenate the lines.
