shared_ptr is now part of the C++11 Standard, as std::shared_ptr. Starting with Boost release 1.53, shared_ptr can be used to hold a pointer to a dynamically allocated array. This is accomplished by using an array type (T[] or T[N]) as the template parameter.
When two or more processes map the same file into memory with the MAP_SHARED option, that single segment is part of both address spaces, and the processes can update its contents concurrently. The POSIX shared memory facility is a simple, formal interface to the use of mmap() to share segments. The IRIX support for shared arenas is an extension of mmap() to make it simpler to create a shared allocation arena and coordinate its use. The SVR4 facilities do not directly use mmap() but have similar results.
