Function problem

[Jace]

I don't know where to input a certain file name into the function so that the function searches for the certain file. If you were trying to find a certain file on your computer, I think this would find it for you. I just don't know how to make it so that whatever you type in is searched for. For reference, here's the function.

WIN32_FIND_DATA file;
    HANDLE search_handle=FindFirstFile("C:\\*",&file);
    if (search_handle)
    {
        do
        {
            std::wcout << file.cFileName << std::endl;
        }while(FindNextFile(search_handle,&file));
        FindClose(search_handle);
}

PS: I already know how to put what you type into a file, but I don't know where to put that file into this fuction.
