Allowed function

Function	Description
gettimeofday	Retrieves the current time with microsecond precision. Useful for timestamping packets and measuring network latency.
exit	Terminates the program immediately. Useful for handling exit conditions or errors gracefully.
inet_ntop / inet_pton	Converts IP addresses between human-readable and network binary formats. Essential for handling IP addresses in networking applications.
nthos / htons:	Converts between host byte order and network byte order for 16-bit integers. Ensures consistency in data representation across different systems.
signal / alarm / usleep	Manages signal handling, timers, and microsecond-level sleep. Useful for implementing timeouts and asynchronous behavior in networking code.
socket / setsockopt / close	Creates, configures, and closes network sockets. Essential functions for establishing and managing network connections.
sendto / recvmsg	Sends data to a specific address and receives data along with sender information. Core functions for sending and receiving network packets.
getpid / getuid	Retrieves the process ID and user ID of the current process. Useful for identifying the running process and implementing security checks.
getaddrinfo / getnameinfo / freeaddrinfo	Resolves domain names to IP addresses and vice versa. Also frees memory allocated by getaddrinfo. Essential for DNS resolution in networking applications.
strerror / gai_strerror	Converts error codes to human-readable error messages. Useful for diagnosing errors encountered during socket operations and network communication.
printf and its family	Outputs formatted text to the console. Useful for displaying information, debugging, and monitoring the program's behavior.
