get_next_line
is a function that reads a line from a file descriptor and returns it as a string. It allows reading text from the file descriptor one line at a time until the end of the file. The function is designed to mimic the behavior of the standard getline()
function and provides a convenient way to read input from files or other sources.
The subject of the project can be found in this link and the wiki explaining my solution to this project can be found here.
- Read a line from a file descriptor
- Returns the line as a string
- Supports reading from multiple file descriptors
To use the get_next_line
function in your project, follow these steps:
-
Copy the following files into your project directory:
get_next_line.c
get_next_line_utils.c
get_next_line.h
-
Include the
get_next_line.h
header file in your source code:#include "get_next_line.h"
-
Call the
get_next_line
function to read lines from a file descriptor.
The bonus part of the project aims to enhance the functionality of get_next_line
. To complete the bonus part, make sure the mandatory part is perfect and then implement the following:
- Use a single static variable to succeed
get_next_line
. - Manage multiple file descriptors, allowing reading from different file descriptors without losing the reading thread.
read
: Used to read data from the file descriptor.malloc
: Used to allocate memory dynamically.free
: Used to free allocated memory.
- The use of the
libft
library is not allowed for this project. - The
lseek
function is not allowed. File reading must be done only once. get_next_line
may have undefined behavior when reading from a binary file.

Note: The BUFFER_SIZE
macro can be modified to adjust the buffer size used for reading. However, during evaluation, the value will be modified to test different buffer sizes.
