Reading a line from a fd is way too tedious

42_GET_NEXT_LINE ↩️

Reading a line from a fd is way too tedious.

About ✍

This project is part of the Rank 01 from 42 Common Core and focuses on creating a function designed to read a single line, delimited by a newline character, by accepting a file descriptor as a parameter. It offers a dynamic and efficient solution for processing and retrieving lines from diverse input sources, including files. When called in a loop, get_next_line returns all the contents of the file, one line at a time until the end of the file is reached. Also, this function works with any size of buffer size specified (as the subject asks).

Prototype 🖥️

char	*get_next_line(int fd);

• fd -> File descriptor indicating the source to read the line from.

Challenges and Learning Objectives 🧠

• Static Variable Implementation: Through this project, we gained valuable insights into implementing static variables within functions, enhancing our understanding of efficient memory management and function behavior.
• File Descriptor Implementation: We learned to effectively utilize file descriptors (fd) in our project, expanding our knowledge of handling input sources and enhancing overall program efficiency.
• Macro Implementation: Understanding the use of macros in functions, such as defining values like BUFFER_SIZE in our header file, allowed for flexible and easily adjustable code configurations.

Norminette 💂🏻

At 42 School, we need to follow some strict rules when writing our code. These rules are described in the Norm and checked by the formidable norminette. Here are some of them:

- No for, do...while, switch, case, goto, ternary operators and variable-length arrays are allowed
- Each function must be maximum 25 lines
- One single variable declaration per line
- You can’t declare more than 5 variables per function
- You can't write more thane 5 functions per file
