Comment (by xijing dai <dxj19831029@…>):

 here is the code:


 {{{
 this->memorySegment = new
 boost::interprocess::managed_windows_shared_memory(
 boost::interprocess::open_or_create, name, size);

 int sizeB = this->memorySegment->get_free_memory();

 }}}

 i allocate 1000000 bytes,
 it said free memory is: 999912, in 32bit.
 in 64 bit, it is: 999848.

 Just wonder, do I need to use different namespace or class name in order
 for managed shared memory to be compatible for 32 and 64 system?

 emm...by the way, how can i reach Ion?

 Cheers
