Скачать или смотреть Reading a file using Memory Mapping in Assembly Language

This video explains how to use memory mapping to access files. A text file is memory mapped using x86 64-bits assembly language and the content is displayed on the screen. I am briefly revisiting the "open" and "close" syscalls (described in the previous video) and then I explain the "fstat" and "mmap" syscalls. The function uses open - fstat - mmap - close. "fstat" is used to obtain the file size.
