[PD-dev] dirty flag for array?

[katja]

Hello,

I'm currently working on a port of a MaxMsp class which operates on a
buffer and sets a dirty flag when something's changed. Does Pd have a
dirty flag for a t_garray buffer, and API methods for setting and
getting the value? From the archives I learn that Thomas Grill had
worked on that in the past but I am not able to find such a thing in
m_pd.h. I just want to be sure, before I erase the corresponding C
lines.

Thanks, Katja
