HOW TO INTERFACE BETWEEN ETHERNET(CYCLONE III) AND PCs(Labtop)

Yes, I did. and Here this code I found.

* get_ip_addr()

*

* This routine is called by InterNiche to obtain an IP address for the

* specified network adapter. Like the MAC address, obtaining an IP address is

* very system-dependant and therefore this function is exported for the

* developer to control.

*

* In our system, we are either attempting DHCP auto-negotiation of IP address,

* or we are setting our own static IP, Gateway, and Subnet Mask addresses our

* self. This routine is where that happens.

*/

int get_ip_addr(alt_iniche_dev *p_dev,

ip_addr* ipaddr,

ip_addr* netmask,

ip_addr* gw,

int* use_dhcp)

{

IP4_ADDR(*ipaddr, IPADDR0, IPADDR1, IPADDR2, IPADDR3);

IP4_ADDR(*gw, GWADDR0, GWADDR1, GWADDR2, GWADDR3);

IP4_ADDR(*netmask, MSKADDR0, MSKADDR1, MSKADDR2, MSKADDR3);

# ifdef DHCP_CLIENT

*use_dhcp = 1;

# else /* not DHCP_CLIENT */

*use_dhcp = 0;

printf("Static IP Address is %d.%d.%d.%d\n",

ip4_addr1(*ipaddr),

ip4_addr2(*ipaddr),

ip4_addr3(*ipaddr),

ip4_addr4(*ipaddr));

# endif /* not DHCP_CLIENT */

/* Non-standard API: return 1 for success */

return 1;

}

So, Dynamic IP or static IP? And I'm really understand clearly how to create code from this program.
