WebShared memory is typically the fastest form of interprocess communication. It provides a memory area that is shared between processes. One process can write data to the area … WebAs we have seen, Boost.Interprocess offers some basic classes to create shared memory objects and file mappings and map those mappable classes to the process' address space. However, managing those memory segments is not not easy for non-trivial tasks. A mapped region is a fixed-length memory buffer and creating and destroying objects of any type …

WebBoost.Interprocess offers offset_ptr smart pointer family as an offset pointer that stores the distance between the address of the offset pointer itself and the address of the pointed object. When offset_ptr is placed in a shared memory segment, it can point safely objects stored in the same shared memory segment, even if the segment is mapped in different … WebSince the C++11 standard, a solution was added by using shared_ptr and weak_ptr, inherited from the Boost library. Weak references are also used to minimize the number of unnecessary objects in memory by allowing the program to indicate which objects are of minor importance by only weakly referencing them.

Webvoid swap (shared_memory_object & moved); Swaps the shared_memory_objects. Does not throw. void truncate (offset_t length); Sets the size of the shared memory mapping. const char * get_name const; Returns the name of the shared memory object. bool get_size (offset_t & size) const; Returns true if the size of the shared memory … WebBoost.Interprocess also offers the possibility of creating non-intrusive reference-counted objects in managed shared memory or mapped files.. Unlike boost::shared_ptr, due to limitations of mapped segments boost::interprocess::shared_ptr cannot take advantage of virtual functions to maintain the same shared pointer type while providing user-defined … WebBoost.SmartPointers provides a helper function boost::make_shared() in boost/make_shared.hpp.With boost::make_shared() you can create a smart pointer of type boost::shared_ptr without having to calling the constructor of boost::shared_ptr yourself.. The advantage of boost::make_shared() is that the memory for the object … downfield post office
