TCP Sockets API

KADAK's KwikNet TCP/IP Stack includes a full featured sockets API with minor adaptations to support re-entrant user applications. The static variable errno is replaced by function kn_errno() which returns the result of the most recent operation on a particular socket.

The KwikNet API uses function names which mimic standard BSD names. The following lists summarize all of the KwikNet sockets services which are accessible to the user.

Receive Services

	kn_recvfrom		Receive data from a socket (gets sender's address)
