Used by

n Task o ISP o Timer Procedure o Restart Procedure n Exit Procedure

Setup Prototype is in file KN_API.H.

#include "KN_LIB.H"

int kn_ifaddress(KN_NETDP netdp, struct in_addr *inadrp);

Description Netdp is a network descriptor pointer, the KwikNet handle used to identify

the network interface of interest.

Inadrp is a pointer to a structure into which the network's IPv4 address in

net endian form will be stored. The BSD structure in_addr is defined

in Treck header file TRSOCKET.H as follows:

struct in_addr {

u_long s_addr; /* IP address (net endian) */

};

Returns If successful, a value of 0 is returned.

On failure, one of the following error status codes is returned:

KN_ERPARAM Parameter netdp does not refer to a valid network or

parameter inadrp is NULL.

KN_ERNETWORK The network interface is not up and hence does not

yet have a valid IP address.

On failure, the storage at *inadrp is unaltered.
