I am using Boost::managed_shared_memory for my project. For allocate and
deallocate we are using boost APIs as show in below example:

shm_controller.reset(new boost::interprocess::managed_shared_memory(
boost::interprocess::open_or_create, shmName, size));void * addr =
shm_controller->allocate(size) ;
shm_controller ->deallocate(addr);

For this I have two question:

1) How can i handle fragmentation in this ? We are doing very frequent
allocation and release.

2) What kind of allocation we are using in boost (slab, slub, slob) ?

First question is very important for me. Please let me know if you want
more info on any of these.

Thanks,
