hey guys,

want to create a mapped binary file into memory, however I not sure how to create the file to mapped into the system. I read documentation several times and realize there is 2 mapped file, 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 trying to allow multi thread program to read an array of large double written in a binary file format. Also what is the different between the mapped file in iostream and interprocess?
