Swig and pointers

[Java and Swing]

(reposting, i was just told how I should properly reply via
groups.google.com)

im sorry, why would it be md_ptr?  what is md_ptr?

i tried..
%include cpointer.i
%pointer_functions(MY_DIGIT, digit_ptr)

ptr = new_digit_ptr()
doIt("a message", ptr)
...doesnt work..still needs a DIGIT **
