I want to create a mapped binary file into memory; however I am not sure how to create the file to be mapped into the system. I read the documentation several times and realize there are 2 mapped file implementations, one in iostream and the other in interprocess.

Do you guys have any idea on how to create a mapped file into shared memory? I am trying to allow a multi-threaded program to read an array of large double written in a binary file format. Also what is the difference between the mapped file in iostream and interprocess?
