Re: Fwd: memory

[Rob Benton <rob benton conwaycorp net>]

I'm pretty sure that...
new calls the "operator new()" function
delete calls the "operator delete()" function
and there are alternate ways of calling new() :

http://www.research.att.com/~bs/glossary.html#Gdelete

As for managing your memory, lots of people will point to one of the 
boost smart_ptr's or something similar :

http://www.boost.org/libs/smart_ptr/smart_ptr.htm

But nobody seems to agree on whether or not those are thread-safe.  What 
I'm getting at is that Gtk::Manage was meant for widgets.  If you have 
objects that are not derived from Gtk::Widget I don't know if that will 
help you at all.  Read through the Memory Management section of the 
Gtkmm book :
