Apparently, LibraryFunctionLoad has an option "AutomaticDelete" with default setting Automatic. The documentation page is silent about how this works. Can I use this to clean up temporary files (as asked in this question)? How does this option work in general?

Reset to default

Making my comments into an answer,

Setting "AutomaticDelete" -> True will cause the DLL file to be deleted when the library is unloaded.

At the moment the default setting of Automatic means False, except when called internally for a Compile-generated DLL.

    $\begingroup$ I don't think it would ever change to a global True, but as with any Automatic setting, the precise meaning could evolve a bit. $\endgroup$

    $\begingroup$ Actually, I'm a bit puzzled why LibraryFunctionLoad was given this option instead of LibraryLoad. What happens if I load two different functions from the same library with LibraryFunctionLoad with separate settings to "LibraryFunctionLoad"? $\endgroup$
