|
* 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.
