Depends on what C code you are working with.  Bidirectional array
arguments are not uncommon in libraries.

Perhaps you can but you would have to write it all yourself.  In
Numarray that work has been done for you.  The three functions
NA_{Input,Output,Io}Array are pretty much all you need for accessing C
libraries with the usual (int size, double *data) interface, whichever
way the data goes.
