[Boost-users] Boost:interprocess 1.36.0 - Minimum size for a shared memory segment

Hi ! which is the minimum number of bytes I have to allocate to construct a managed shared memory? Or how can I calculate it? I did some tests and I believe is 112 bytes for 32 bit machines and 224 bytes for 64 bit, am I right ? And for the allocators? What I want to do is set the size of the shared memory smaller than I can, knowing the dimension of the variables I want to put in; even if the code is compiled in 64 bit or 32 bit machines. Thank you, Federico
