You should only set the flag if the datagram you’re sending is a direct response to a datagram you just received from the same peer. If you’re sending an initial request, or sending a datagram in response to some other event (like user input, or a timeout) then you should not set the MSG_CONFIRM flag.
After importing <netinet/if_ether.h>, you should edit it and change the line #include <net/if_arp.h> to #include “if_arp.h” and then import <net/if_arp.h> in your project as well. This should fix that error. Anyway the headers you need to import to compile the code you posted are: #include “if_ether.h” #include “route.h” #include “if_arp.h” #include “if_dl.h” Hope this helps … Read more
