Session 8 File Handling in Linux| Linux Application Programming

In this session, we’ll look at the file handling APIs of GNU/Linux and explore a number of applications to demonstrate the proper use of the file handling APIs. We’ll look at a number of different file handling functions, including character interfaces, string interfaces, and ASCII-mode and binary interfaces. The emphasis on this session will be to discuss the APIs and then use them in applications to illustrate their use.
File handling within GNU/Linux is accomplished through the standard C Library. We can create and manipulate ASCII text or binary files with the same API. We can append to files or seek within them.
In this session, we’ll look at the fopen call (to open or create a file), the fwrite and fread functions
