This project serves as a learning exercise in handling file descriptors and efficiently managing buffer operations in C. The goal of the project is to implement a function, get_next_line, which reads a single line from a file descriptor and handles subsequent calls effectively, even with multiple file descriptors.

General Functions

• The get_next_line function is the core of this project. It reads a single line from a given file descriptor, returning it as a dynamically allocated string. This function is designed to handle buffers, partial reads, and newlines efficiently. It ensures that subsequent calls continue from where the last read ended, supporting continuous reading from multiple file descriptors simultaneously.

Utility Functions

• The utility functions support the operation of get_next_line. These functions perform tasks such as managing buffers, handling memory allocation for dynamic strings, and splitting strings at newline characters. They ensure that get_next_line operates efficiently without memory leaks or errors.
