Re: Passing NULL pointer through XS without "Use of uninitialized value in subroutine entry"

Does it help if you change your code to not pass a reference to undef, but instead just pass undef?

my $bar = Foo::create_bar($foo);

That seems like a more straight-forward representation of C's NULL to me.

If I do that, with no other changes, I get the error: "create_bar() -- foo is not an SV reference".	[reply]
