getting source codes as starting point

klaus filip's icon

hi there,
i am wondering if i can get hold of the source of max-externals, that are not in the example list of the MaxSDK.
namely i would like to see "pvar.c", "forward.c", "send.c" and "autopattr.c".
i want to create an object that can be described as autopvar with implemented send option.
i will have help by an experienced c-programer.

best regards
klaus
