Final answer:
Attempting to write to a socket that has received a FIN signal will typically result in an RST packet being sent, potentially terminating the connection and causing a SIGPIPE signal or an EPIPE error.
Step-by-step explanation:
When a process attempts to write to a socket on which the FIN signal has been received, it signifies that the other end of the connection has closed its half of the connection. The TCP protocol allows for half-closed connections, where one side can continue to send data until it's ready to close, even if the other side has finished sending data. However, depending on the implementation of the network stack, if a process writes to a socket that has been closed by the peer (FIN received), the local end will typically send an RST (Reset) packet, terminating the connection completely. This situation could also raise a SIGPIPE signal (if the writing process is not ignoring or catching it), and the write operation could fail, typically with an EPIPE error.
