This 42 school project is aimed at reading a line from a file descriptor. If called in a loop, get_next_line should return the entire content one line at a time, until the end of the file is reached. When compiling it, we should be able to modify the buffer size.

Grade : 125/100.

cc get_next_line.c get_next_line.h get_next_line_utils.c main_for_test/main.c

cc *_bonus.c main_for_test/main_bonus.c

BUFFER_SIZE can be changed at compilation using the command -D BUFFER_SIZE. For instance to read byte-by-byte:

cc -D BUFFER_SIZE=1 get_next_line.c get_next_line.h get_next_line_utils.c main_for_test/main.c

To test with a file : ./a.out to execute. Otherwise in case of manual input test, you will need to use main_manual_input.c execute with ./a.out /dev/tty and then entire your text - stop at any moment with ctrc + c

here is result of the bonus expected : one line from each fd at a time.

We are using linked lists as a static variable to read each buffer_size number of bytes from the file (mapped by the fd) into each node as long as there is text or we encounter a \n. we then handle the last node to only keep the characters placed after \n that were read in the last buffer. We then clear the list, make it match the new node with characters after the \n, so that next call of get_next_line() will build the next linked list on top of the previous call words happenign after the \n ... and so on until we reach end of file.
