Hello:

I want objects of a class to be allocated from shared
arena. I have overloaded operators new and delete as
follows:

class CTruck
{
   public:
        CTruck();
        ~CTruck();
        void *operator new(size_t);
        void *operator new(size_t, void *arena);
        void operator delete(void *);
   ...
}

void *CTruck::operator new(size_t size)
{
    return pfMalloc( size, pfGetSharedArena());
}

void *CTruck::operator new(size_t size, void *arena)
{
    return pfMalloc( size, arena );
}

void CTruck::operator delete(void *p)
{
    pfFree(p);
}

This seems to work. Is it the _right_ way to allocate
objects from shared arena?

I'm wondering if I should derive this class and others
from pfObject or pfMemory to get this allocation behaviour
automatically.

Thanks
