NAME
     net_addrcmp - compare socket address structures
 
SYNOPSIS
     #include &lt;netdb.h&#62;
 
     int
     net_addrcmp(struct sockaddr *sa1, struct sockaddr *sa2);
 
DESCRIPTION
     The net_addrcmp() function compares two socket address structures, sa1
     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-&#62;sa_len is less than or greater than
     sa2-&#62;sa_len, respectively.
 
     Next, the sa_family members are compared.  If they do not match,
     net_addrcmp() returns -1 or 1 if sa1-&#62;sa_family is less than or greater
     than sa2-&#62;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 &#62;0 or &lt;0 is returned.
 
HISTORY
     A net_addrcmp() function was added in OpenBSD 2.5.
 
BSD                              July 3, 1999                              BSD
