Actually, I just found a hack. Edit your .pd file with a text editor in
this way:
1. replace "loadbang;" by "r \$0-initbang;"
2. add a line at the very end that says just "$0-initbang bang;", no
backslash, no "#X obj", no object position.
This works in all versions of Pd. If you don't understand how this works,
it's normal. Furthermore, to edit this patch, -noloadbang does not work
anymore, so you have to undo step 2 before any edit in pd, and redo it
after any edit in pd.
So, yes, it can be done in Pd ! But my main point was that it's usually
much less trouble to write the damn thing in C.
