How to read data from a Memory Mapped Object created in C++ program

A memory map object has been created using CreateFileMapping function in a C++ program, the name of the memory map object is '("Local\\MyFirstFileMappingObject")'. Some data of 256 bytes is written by the C++ program using CopyMemory function. Now I want to read/use the data written by the C++ program using memory map object in my Simulink models or in the Matlab base workspace. Example: Lets say a string "Some data string" is written by C++ program In my Matlab program How to read the data "Some data string" ?

Note: This can be fixed by using a file but I am interested in knowing about reading/writing data using memory map objects.
