HI all,
I use DC 9.1 on a RCM3200.
I've been experimenting the runtime ip address change from DHCP to
Static & vice-versa on a simple program.
After toggling the choice 4 times the program crashes giving the
following error on a message box.
"Run Time Error: XMEM allocation failed .. ( out of memory)
Address fd: e855"
Occasionally this address changes slighlty.
Any clues as to why this would happen?
Regards
Nil
DHCP <-> STATIC IP

Are you calling sock_init() more than once? ------

Sorry for the late reply as I was out of office.
I figured out calling http_init(); each time after a runtimeIPchange
() is not healthy. I initially did this because the web pages
disappeared after a runtime IP change.
Just call only tcp_reserveport(80); only after a Runtime IP change
and everything works ok.
Thanks Scott for the suggestion.

Nil,
Perhaps you could elaborate a bit on how you are able to switch back and
forth between DHCP and Static IP. I've never been able to do that
successfully without rebooting each time.

Hi Steve,
DHCP<->Static and vice-versa works well at runtime with no rebooting.
I define TCPCONFIG as 6
At bootup I call two functions.
1.loadNetwork(char *ip,char *sub, char *gw, int dhcp)
2.runtimeIPChange(char *ip,char *sub, char *gw, int dhcp)
void loadNetwork(char* ip, char* sub, char* gw, int dhcp){
/*Need the following if statement due to a bug*/
if(!dhcp){
ifconfig(IF_ETH0, IFS_IPADDR, aton(ip),IFS_NETMASK, aton(sub),
IFS_ROUTER_SET, aton(gw),IFS_DOWN,IFS_END);
sock_init();
ifup(IF_ETH0);
}
runtimeIPChange(ip, sub, gw, dhcp);
http_init();
tcp_reserveport(80);
}
void initInterface(char* ip, char* sub, char* gw, int dhcp){
auto DHCPInfo * di;
if(dhcp){
ifdown(IF_ETH0);
ifconfig(IF_ETH0, IFG_DHCP_INFO, &di, IFS_END); // Get whether
interface is qualified for DHCP
printf("Interface IF_ETH0 is %squalified for DHCP.\n",
di ? "" : "NOT ");
ifconfig(IF_ETH0,IFS_DHCP, di != NULL, // Use DHCP if interface
is qualified for it
IFS_DHCP_TIMEOUT, 15, // Specify timeout in seconds
IFS_DHCP_FALLBACK, 1, // Allow use of fallbacks to static
configuration
IFS_END);
if (di){// Specify fallbacks for DHCP...
ifconfig(IF_ETH0,IFS_IPADDR, aton(DROPIP),
IFS_NETMASK,aton(DROPMASK),
IFS_ROUTER_SET, aton(DROPGW),
IFS_END);}
sock_init();
ifup(IF_ETH0);
}
else{ // STATIC IP
printf("Forced to use static IP");
ifconfig(IF_ETH0, IFS_DHCP, 0, IFS_END);
ifconfig(IF_ETH0, IFS_IPADDR, aton(ip),
IFS_NETMASK, aton(sub),
IFS_ROUTER_SET, aton(gw),
IFS_UP,
IFS_END);
}
tcp_reserveport(80);
}
DROPXX values are fallback if DHCP server is not present. Now, during a Runtime IP change, Call only the initInterface(char*
ip, char* sub, char* gw, int dhcp) Method.
I tested this by having key presses, 0-9 and by going true a case
statement, and printing the ip_print_ifs();
Seems to switch fine with no problems.

Nil,
According to "the manual", http_init() MUST be called
after sock_init(). But in your code, I don't see
sock_init() being called at all on boot up.
Is runtimeIPChange your procedure, as apposed to a DC
lib function? Maybe that's where sock_init() is being
called?
It also looks to me like sock_init() will get called
more than once when you switch between Static IP and
DHCP. I thought sock_init() could only be called one
time, otherwise horrible things happen to your
program.

Hi Steve,
Yes, http_init() should be called after sock_init()
If you look closely at the code you will see that sock_init() is
called before http_init()
BOOTUP====================
1. Static IP - > sock_init() is called at loadNetwork() before
runtimeIPChange() is called
2. DHCP IP -> loadNetwork simply calls runtimeIPChange() and sock_init
() is called there.
So no matter what type, sock_init() is called before http_init() is
called. AT RUNTIME==================
Only call the runtimeIPChange() function. Yes this is a method of my
own and not of ZWorld.
It does call the sock_init() each time activating a DHCP address but
I think because the interface is 'down' it does not make a difference.
(try to remove it and see if fails *grin*)
Going from a DHCP to a static, it does not call sock_init() at all.
Going either way, both calls tcp_reserveport(80) though.
After this code I've swapped between the two types manytimes
manually, but no crashes. So the 'horrible' things are undiscovered
yet. If you discover anything please let me know too. :)
