Member Function Documentation

◆ _q_abortConnectionAttempt()

void QAbstractSocketPrivate::_q_abortConnectionAttempt ( )

This function is called after a certain number of seconds has passed while waiting for a connection. It simply tests the connection, and continues to the next address if the connection failed.

◆ _q_connectToNextAddress()

void QAbstractSocketPrivate::_q_connectToNextAddress ( )

Called by a queued or direct connection from _q_startConnecting() or _q_testConnection(), this function takes the first address of the pending addresses list and tries to connect to it. If the connection succeeds, QAbstractSocket will emit connected(). Otherwise, errorOccurred(ConnectionRefusedError) or errorOccurred(SocketTimeoutError) is emitted.
