[Closed] Pflow particle export to a file with script or sdk??

Hi

I have tight schedule and i must export particles (position and age) to binary file for my own volume rendering software.
I have done this with two scripts. One is finalstep script that puts particle data to global arrays and the second one is the control sript that does the file writing and advances the frame. This works OK, but is quite slow, because i need some 100k-1000k particles for this to work.

Is there any way do it faster with a script? Can it be done that from pflow directly to write the file?

I am not yet started to look in max sdk. I would like to this with that. Any help. What kind of plugin i should make. Have someone done something that can be used as a skeleton for this one?
