nv_addr

The nv_addr data structure specifies the IPX address. It is defined in the nv.h

header file.

s_net[4]

network address portion of the IPX address for the host.

s_host[6]

node address portion of the IPX address for the host.

s_port

IPX socket (port) number portion of the IPX address for the host.

struct nv_addr {

unsigned char s_net[4];

unsigned char s_host[6];

unsigned short s_port;

};

Note. The s_port IPX socket number is different from the term socket used to denote the

end point of a network connection. The IPX socket number is equivalent to the TCP/IP

port number.
