IIRC there was a documentation somewhere about (private) creation arguments (position and meaning) for dynamic patching ; for [floatatom] and iem GUI objects. I can't find it anymore. I need it to parse pd files (inside another software). I could search into the sources, but if it is already done...

Should be here..... https://puredata.info/docs/developer/PdFileFormat ...... but the whole site is unreachable right now.
It used to be included in Pd extended source code..... another loss....
Here it is....... pdfileformat.zip

Thanks!
