Final answer:
When a process tries to write to a socket that has received an RST packet, it typically results in an error, as the connection has been terminated by the remote side. This may lead to signals or exceptions, requiring error handling to manage the situation.
Step-by-step explanation:
When a process writes to a socket that has received an RST (Reset) packet, which is a signal that the other side of the connection has aborted the connection, typically an error occurs because the socket is no longer in a state where it can send data. If the local socket endpoint still has sending capability and was not the one that sent the RST, attempting to send data may result in a signal such as SIGPIPE being generated, or an EPIPE error if the signal is ignored. On a higher level, such as in a web application, this may be seen as an exception when trying to write to a socket. In either case, proper error handling code is required to handle this situation correctly, such as re-establishing the connection or communicating the error to the user.
