this file. This function is more secure than [temp_file]: there
|
|
is no risk that the temporary file will be modified (e.g. replaced

by a symbolic link) before the program opens it. The optional argument
|

[mode] is a list of additional flags to control the opening of the file.

It can contain one or several of [Open_append], [Open_binary],
