NET_ADDRCMP(3)            OpenBSD Programmer's Manual           NET_ADDRCMP(3)

     net_addrcmp - compare socket address structures

     #include <netdb.h>

     net_addrcmp(struct sockaddr *sa1, struct sockaddr *sa2);

     The net_addrcmp() function compares two socket address structures, sa1
     and sa2.

     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,

     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.

     A net_addrcmp() function was added in OpenBSD 2.5.

OpenBSD 2.6                      July 3, 1999                                1
