| 3 | * Application layered TCP connection API (to be used from TCPIP thread)\n
|
---|
| 4 | * This interface mimics the tcp callback API to the application while preventing
|
---|
| 5 | * direct linking (much like virtual functions).
|
---|
| 6 | * This way, an application can make use of other application layer protocols
|
---|
| 7 | * on top of TCP without knowing the details (e.g. TLS, proxy connection).
|
---|
| 8 | *
|
---|
| 9 | * This file contains the base implementation calling into tcp.
