Looked promising, but not quite good enough. I dedined:

typedefoffset_ptr

...

my_offset_ptr; typedef basic_managed_shared_memory ,iset_index> compat32_shared_memory;

in the win64 process I do

compat32_shared_memory segment(create_only, SEGMENT_NAME, SEGMENT_SIZE); comm *command = segment.construct<comm>( "CommandBlock" )();

in the win32 process in do

compat32_shared_memory segment(open_only, SEGMENT_NAME); std::paircom = segment.find<comm>("CommandBlock");

the "find" never returns.

The code works fine if both processes are win32 or both are win64 Am I on the right track?

Sorry about my previous reply. I just noticed that the definition for my_offset_ptr must be binary compatible in 32 and 64 bit processes so std::ptrdiff_t should not be used (as it's 32 bit in 32 processes and 64 bit in 64 bit processes). Try with something like: typedef offset_ptr< void , boost::int32_t , boost::uint64_t > my_void_offset_ptr; or typedef offset_ptr< void , boost::int64_t , boost::uint64_t > my_void_offset_ptr; Good luck!
