Hi,

which unix function allows me to split an ip address
returned from gethostbyname into octets ?

Thank you,

What exactly do you want to do?

struct hostent *k = gethostbyname("www.google.com");

        char packet[10];
        packet[0] = 5;
        packet[1] = 1;
        packet[2] = 0;
        packet[3] = 1;
        packet[4] = 
        packet[5] = 
        packet[6] = 
        packet[7] = 
        packet[8] = 0;
        packet[9] = 80;

In packet[4] 5,6 and 7 I have to put the octets of the ip
address of google to form a socks5 request as stated in the
rfc section 4:
http://rfc.net/rfc1928.html

Thank you for replying,

Why not memcpy(packet + 4, k->h_addr, 4)?

Of course, you should make sure that 4 is actually the size of the
address.  It could be an IPv6 address.  Multiple addresses should also
be handled properly.  Just using the first is normally reasonable, but
there may be situations where this isn't the right thing.
