Chapter 8. File Access and Processing

Any commercially available programming language is able to communicate with disc data files. This communication process depends on the operating system under which the language is used. UNIX is the operating system under which C was developed originally. Nowadays, C compilers are available under most of the major operating systems. In fact, most of the I/O functions in C behaves in a consistent way across operating systems, though all the operating systems do not provide all the facilities available in UNIX. In this chapter, we will discuss how data disc files are used in C.

Introduction

There are two levels with which reading and writing data stored on disc can be accomplished. They are high-level disc I/O ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
