get_next_line

This project is about programming a function that returns a line read from a file descriptor.

char *get_next_line(int fd);

External functions allowed:

• read
• malloc

Repeated calls of the function allows us to read the entirety of a file.

get_next_line returns the line that was read or NULL if an error occurred.

Bonus part

Your get_next_line() can manage multiple file descriptors at the same time. For example, if you can read from the file descriptors 3, 4 and 5, you should be able to read from a different fd per call without losing the reading thread of each file descriptor or returning a line from another fd. It means that you should be able to call get_next_line() to read from fd 3, then fd 4, then 5, then once again 3, once again 4, and so forth.
