get_next_line

Description

get_next_line is a custom implementation of the classic function for reading lines from a file descriptor in C. This particular implementation uses a linked list where each node contains a single character from the line. This method ensures efficient memory management and ease of manipulation for each character read.

Features

• Reads a line from a file descriptor.
• Uses a linked list data structure where each node stores a single character.
• Efficient memory management and dynamic line length support.
• Handles different buffer sizes and multiple file descriptors.

Algorithm

1. Node Structure: Each character read from the file is stored in a node of a linked list. The node contains:

   • A character.
   • A pointer to the next node.

2. Reading Characters: Characters are read from the file descriptor one at a time and stored in nodes.

3. Building the Line: As characters are read, they are added to the linked list. The line is constructed by traversing the linked list from the head node to the end.

4. Line Termination: The end of a line is determined by encountering a newline character (\n) or the end of the file.

Usage

char *get_next_line(int fd);
