/** * @file * Application layered TCP connection API (to be used from TCPIP thread)\n * This interface mimics the tcp callback API to the application while preventing * direct linking (much like virtual functions). * This way, an application can make use of other application layer protocols * on top of TCP without knowing the details (e.g. TLS, proxy connection). * * This file contains the base implementation calling into tcp. */ /* * Copyright (c) 2017 Simon Goldschmidt * All rights reserved. * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * * 1.
