But i am getting the following defintion for the function.
Sorry, I wasn't reading your post correctly. I was referring to open_shared_object. For me, the following stripped down example throws already: #include <boost/interprocess/managed_shared_memory.hpp> using namespace boost::interprocess; int main (int argc, char *argv[]) { managed_shared_memory segment(open_or_create, "MySharedMemory", 999999999); } $ ./a.out terminate called after throwing an instance of 'boost::interprocess::interprocess_exception' what(): Aborted This is due to an illegal size for the shared memory area on my plattform (linux): $ cat /proc/sys/kernel/shmmax 33554432 Shouldn't the exception report "invalid argument" if size > SHMMAX? manish4gupta, what system are you running the example on?
