No. The exam’s automated grader will flag any artificial delays as inefficient. You must use sigprocmask and proper synchronization.
: The server must handle multiple clients simultaneously without blocking. This usually requires mastering the select() function to monitor multiple file descriptors at once.
: The server must be non-blocking; if a client is "lazy" and doesn't read, you must not disconnect them or hang the server. Broadcasting : When a client sends a message, the server must prepend client %d: is their ID) and send it to all connected clients. Specific Formatting Rules 42 Exam 06
You are often provided with a main.c file (roughly 80–100 lines) that contains necessary boilerplate code and helper functions like extract_message and str_join .
Before submitting, test with multiple clients and multi-line messages to ensure the moulinette (the automated grader) doesn't fail you on edge cases.

You must manage three structural elements when working with select() :
To succeed, your code should follow a clear, iterative flow: Socket Initialization : Create a socket using , bind it to a port with , and set it to listen mode with The Main Loop Broadcasting : When a client sends a message,
: Managing connections and communication via the TCP protocol .
Writing buffer-splitting logic using raw pointers, strlen , and strcat without standard library conveniences is error-prone. Practice writing clean buffer management helper functions.
