Re: [Boost-users] [interprocess] access dynamically accessed shared region in another process

To do this, I first create a shared segment and then a dynamic area in it. like this:

struct transfer_buffer { void *buf; size_t bufsize; boost::interprocess::interprocess_mutex mutex; size_t dmember; }

I only quickly looked at your code, but I think that your void* pointer is invalid in the second process.

Take a look at boost::interprocess::offset_ptr and use it in place of void*.

Thanks for the quick reply, Dan. Yes, all pointers placed in shared memory should be offset_ptr as explained here: http://www.boost.org/doc/libs/1_38_0/doc/html/interprocess/sharedmemorybetwe... Regards, Ion
