WIN32 Memory Mapping

Question 1

Advantages of memory-mapped files

Answer 1

• Allows the programmer to manipulate datastructures without having to deal with I/O functions, the OS manages all the data movement, possibly optimizing
• Memory-mapping makes application that interact with disk files significantly faster, memory-based algorithms can be applied to files.
• No need to manage buffers
• Multiple process can share the same memory-mapped segment with consistency.
• The mapping does not expand if the file size increases (growing files must be remapped);
