and sa2.
RETURN VALUES
If sa1 and sa2 are for the same address, net_addrcmp() returns 0.
The sa_len fields are compared first. If they do not match,
net_addrcmp() returns -1 or 1 if sa1->sa_len is less than or greater than
sa2->sa_len, respectively.
Next, the sa_family members are compared. If they do not match,
net_addrcmp() returns -1 or 1 if sa1->sa_family is less than or greater
than sa2->sa_family, respectively.
Lastly, if each socket address structure’s sa_len and sa_family fields
match, the protocol-specific data (the sa_data field) is compared. If
there’s a match, both sa1 and sa2 must refer to the same address, and 0
is returned; otherwise, a value >0 or < 0 is returned.
HISTORY
A net_addrcmp() function was added in OpenBSD 2.5.

NAME
ns_addr, ns_ntoa - Xerox NS(tm) address conversion routines
SYNOPSIS
#include < sys/types.h>
#include < netns/ns.h>
struct ns_addr
ns_addr(char *cp);
char *
ns_ntoa(struct ns_addr ns);
DESCRIPTION
The routine ns_addr() interprets character strings representing XNS
addresses, returning binary information suitable for use in system calls.
The routine ns_ntoa() takes XNS addresses and returns ASCII strings rep-
resenting the address in a notation in common use in the Xerox Develop-
ment Environment:
< network number>. < host number>. < port number>
Trailing zero fields are suppressed, and each number is printed in hex-
adecimal, in a format suitable for input to ns_addr(). Any fields lack-
ing super-decimal digits will have a trailing ‘H’ appended.
