Re: [Boost-users] [interprocess] 32 to 64 bit ?

The code is the same as in my 32 - 32 bit versions and known to work. Now I'm wondering, is this supposed to work or is 32 to 64 bit transfer not supported at all? Is this a bug or a feature? Do I have to have both applications in a 64 bit version?

There is no support for 32bit-64bit communications. You would need to use much lower level utilities, like mapped_regions to do that. Internal structures have platform-dependent sizes (e.g.: offset_ptr needs to be bigger in 64 bit systems because it has to address much bigger address space).
