This project is about programming a function that allows you to read content line by line. This is done by returning a line read from a file descriptor.

The primary function in this project is get_next_line, which reads from a file descriptor (fd) and returns one line or NULL.

Return Value:

• char *: The string containing a line read by the function.
• (null): Either an error occurred or reached EOF (End Of File).

This project includes several helper functions that the get_next_line function utilizes:

• strjoin: Function to concatenate strings.
• strlen: Function to find the length of a string.
• strchr: Function to find the first occurrence of a character in a string.
• strdup: Function to duplicate a string.
• substr: Function to extract a substring from a string.
