This implementation does not use tempfile.mkstemp to avoid having a file handle. If the code using the returned path wants to delete the file itself, windows requires that no program has a file handle to it. Parameters ---------- filename : str (optional) suffix of the created file. return_filelike : bool (default False) if True, returns a file-like which is *always* cleaned. Necessary for savefig and other functions which want to append extensions. **kwargs Additional keywords are passed to open().
