tapping into STL mempool

[Sandeep Srinivasa]

hi,
I have a software which uses huge STL data structures. Since STL
retains its mempool, the memory that is used is not given back to the
system.

Now consider a simple class:

MyClass *c1=new MyClass;

Suppose I do a million of these too, then it takes up all of the memory
left over.
Two questions:

1. Can I use STL's memory pool to allocate memory for this class as
well - Is there a piece of code I can look to see?
2. How do I **verify** that I am using STL's memory pool - I have
valgrind at my disposal. I dont want to make a mistake and think
everything is working hunky dory.

Thanks in advance

I think you're referring to a particular implementation of STL, since
there is no requirement in the C++ Standard to hold on to memory. You'll
have to ask the folks who support your implementation.
