hi -

(1) Is there some general guidelines for wrapping a C library, say
this C library has a number of .h files that defines constants,
structures, and function declaration. If I don't necessarily know
which function to export, so is this OK (or a good idea) to use
something like:

%include "cmd.h"
%include "msg.h"
...

(2) In the case of a function is using a generic libc structure, such
as struct timeval, should I copy this structure out and put it into
interface definition file, or there are better ways of doing this?
(with pasting this structure, it seems the wrapping doesn't work).


(3) Say, if I do copy and paste into interface definition file, why
the generation reports twice the warning message on each class
correction?

rproxy.i:13: Warning(801): Wrong class name (corrected to `Timeval')
rproxy.i:13: Warning(801): Wrong class name (corrected to `Timeval')


thanks
