Re: [Boost-users] does ptr_* solves this?

My problem is that when an object is removed from the container, I have to explicitely deallocate it from my allocator, but the static info was lost, so I cannot do

my_alloc::deallocate(1,oj);

Just to point out, you probably want to use your allocator's construct and destroy methods too.

I've asked in boost irc channel, and someone told me ptr_* boost libraries solve this problem, is this correct?

I don't think that the ptr_ ones will, but shared_ptr allows you to specify a custom deleter at construction, which seems to be to be just what you need. ~ Scott
