I think Jacob was suggesting something like this:
function create_data(API::Ptr{None}, family=5, geometry=1, mode=0,
par::Ptr=C_NULL,
wesn::Ptr=C_NULL, inc::Ptr=C_NULL, reg=0, pad=2,
data::Ptr{None}=C_NULL)
Have you tried that? (The Ptr types are loosened by removing the type
parameter).

the type annotation to test this theory.
