Hi Robert,
This is the memory management patch, without the callback. If you are
interested in... use it. :-)
Regards,
Vincent.

Hi Robert,
osgcallback already implements a ReadFilecallback... so I don't know
if it will be useful to make an example.
If you want I can make a wiki page, but for that could you tell me
were to put it ?
Thanks.
Regards,
Vincent.

Yay! :-)
Would you (and osg) be interested in having it ? I can submitt in
directly
in osg src.
It's probably a bit too domain specific to be part of the OSG, perhaps
an example with it in would be good, or an example on the wiki so that
if others want to use the same techniques then they could deploy.
I implemented if for WIN32 only, so someone should implement the other
version...
For the moment, it uses psapi.lib ... not very portable but maybe
someone
can help be making it portable and without
other dependencies.
I don't even know was psapi.lib is... ;-)
Robert.
