There comes a time when you want to read and write to and from files so that the information is shared between processes. ... Wouldn't it be easier if you could just map a section of the file to memory, and get a pointer to it? Then you could simply use pointer arithmetic to get (and set) data in the file. Well, this is exactly what a memory mapped file is. ... Before mapping a file to memory, you need to get a file descriptor for it by using the open() system call: . ... mmap() . ... open() . ...
