Ensuring the server doesn't "hang" while waiting for a single slow client. Buffer Management:
Recommend specific testing configurations to check for memory leaks.
This is not just about getting a simple echo server working; the mini_serv must handle complex scenarios. As one student researcher noted, the project involves creating "an interactive shell for 42 School, featuring practice exercises and a user-friendly menu for Ranks 02-05". The most reliable client for testing is Netcat ( nc ), which can be used in multiple terminal windows to simulate several clients connecting to your server simultaneously. 42 Exam 06
The exam is typically auto-graded. Your final score depends on the completeness and correctness of your implementation. The code must compile and run without errors, and follow the specifications precisely.
Clients do not always send data all at once. A single message might arrive in fragments, or multiple messages might arrive glued together in a single packet. You must implement a robust buffering mechanism to store partial data until a newline character ( \n ) is detected.

A successful Exam 06 template relies on a clean, centralized event loop. Step 1: Initialization and Setup
You should be able to write the socket initialization and select() loop blindly. Practice this until it becomes muscle memory. As one student researcher noted, the project involves
To prevent this without resorting to multi-threading, Exam 06 requires the use of select() . The select() system call allows a program to monitor multiple file descriptors, waiting until one or more of them become "ready" for an I/O operation (e.g., input possible, or writing won't block).
