Finding All Devices

This simple code segment issues a find on all devices and then prints out each device

using the print_info function code segment from the previous page.

This code segment allocates space for ten devices and then performs a find for

devices. If the return code is greater than zero, then the function successfully found

the number of devices returned.

Notice that we have to explicitly Free() the allocated buffers, and then delete the class

for proper memory management.

int main(int argc, char* argv[])

{

CCEthernet *a;

ceth_device_p b;

ceth_device_p d;

int c;

int i;

a = new CCEthernet();

b = a->Alloc(10);

c=a->find_devices(Sealevel_All_Devices,10,b);

if(c<0)

{

printf("Error %d\n",c);

goto end;

}

printf("Found %d\n",c);

d=b;

for(i=0;i<c;i++)

{

dump_out(d);

d++;

}

end:

a->Free(b);

delete(a);

return 0;

}
