Code:
memset((void*)icmpdata, 0, 60);
All you need is the address of the icmp data element in the structure that you are going to send.

memset() function fills the first n bytes of the memory area pointed to be s with the constant byte c. so the memset does the 123 to 0000000000123 or to 1230000000000. i want to do the second one
