The return value is a pair (fd, name) where fd is the file descriptor returned by os.open, and name is the filename. A function called by the user to create and return a unique temporary file. The return value is a pair (fd, name), where fd is the file descriptor returned by os.open and name is the file name.

If 'prefix' is not None, the file name will start with this prefix, otherwise the default prefix will be used. If 'dir' is not None, the file will be created in that directory, otherwise a default directory is used. If 'dir' is not None, the file will be created in that directory, otherwise the default directory will be used. If 'text' is specified and true, the file is opened in text mode.

This file can only be read and written by the user ID created. If the operating system uses permission bits to indicate whether the file is executable, no one can execute the file.
