Exam 06 usually tests than previous exams, often including:
If data is received, append it to that client's specific read buffer. Phase 3: Message Parsing and Broadcasting
The Moulinette resets /dev/shm/ . Use unique names like /sem_philo_<pid> to avoid conflicts.
In the 42 curriculum, there are usually 6 core written exams (Exam 00 through Exam 06), though numbering varies slightly by campus. is the final C exam. Unlike Exam 02 (pointers and memory) or Exam 03 (mini-shells), Exam 06 focuses almost exclusively on Concurrency . 42 Exam 06
: You need to handle "partial" messages. If a client sends a message without a newline, you must buffer it until a is received before broadcasting. Resource Management : Keep track of the function and ensure you properly sockets and free memory upon disconnection.

: Failing to close a file descriptor upon a client disconnect will eventually exhaust the server's limit, causing it to fail the grading script. In the 42 curriculum, there are usually 6
Create a helper function to send messages to all connected clients except the sender.
What are you seeing (segmentation fault, frozen server, lost messages)? Are you struggling with the buffer management logic?
