c++ - WIN32_FIND_DATA-获取绝对路径

我正在使用这样的东西:

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);

它将在相对目录./test/*中打印每个文件的名称。

是否有任何方法可以确定此目录的绝对路径，就像realpath()在Linux上所做的那样，而无需涉及任何BOOST等第三方库？我想打印每个文件的绝对路径。

最佳答案

请参见 GetFullPathName 函数。
