get_next_line

📚 Description

get_next_line is a project at 42 that introduces dynamic file reading in C. The goal is to implement a function capable of reading a file line by line, regardless of the length of the lines or the BUFFER_SIZE used for reading.

This project deepens the understanding of file descriptors, static variables, dynamic memory management, and efficient buffer handling.

🚀 Features

get_next_line implements the ffollowing functionalities :

1. Dynamic File Reading

The function get_next_line(int fd) is capable of :

• Reading from a file descriptor (fd).
• Extracting one complete line at a time, including the newline (\n).
• Managing multiple file descriptors simultaneously.
• Preserving the remainder of the buffer for the next call.

2. Memory Management

• Uses static storage to retain unprocessed data between function calls.
• Efficiently handles concatenation of partial reads with ft_strjoin().
• Uses ft_memmove() (or other function) to shift remaining data in the buffer after extracting a line.
• Ensures proper memory allocation and freeing to prevent leaks.
