Reading a line on a file descriptor

Get Next Line

Summary

This project aims to develop the get_next_line function, capable of reading lines with a limited buffer size from a file descriptor. This project is written in C.

Git Repository Contents

• get_next_line.h: Header file containing the prototype of the get_next_line function.
• get_next_line.c: Implementation of the main function.
• get_next_line_utils.c: Utility file containing additional functions necessary for the implementation of get_next_line.

Acquired Skills

C Programming

• Development of a complex function in the C language.
• Adherence to the 42 School C coding standard to ensure code quality and readability.
• Robust handling of undefined behaviors and error cases.

Compilation and Makefile

• Makefile to automate the project compilation.
• Use of flags -Wall, -Wextra, and -Werror.
• Use of flags -g3 and -fsanitize=address for debugging.

Memory Management

• Dynamic memory allocation using malloc.
• Freeing memory once operations are completed or in case of errors to prevent leaks.
• Use of valgrind to check for residual memory leaks.

String Handling

• Reading and storing strings.
• Parsing the string to check for the end of a line defined by a newline character \n or end of file EOF.
• Reuse of the file descriptor to read the file line by line once the function is recalled, returning the remainder of the previous line if a newline is found.

Static Variables

• Definition of a BUFFER_SIZE before compilation to set a constant buffer size.
• Use of a static variable to store the remainder of the previous line if a newline is found.

File Handling

• Reading lines from a file descriptor.
• Handling various use cases, such as end of file or reading errors.
• Multiple file descriptors handling with a constant array of strings.
