Please, could anyone tell me what am i doing wrong? This is a weird error, gcc gives me no warnings.
Oh!, i changed the memcpy function to strncpy, strcpy, and i keep getting the same SIGSEGV.
I'll appreciate any answers, thank you.
From your post it looks like arpmsg is a struct tag not an instance of that type...and if you have a variable of that type calld aprmsg then you are using the wrong operator to access its members...
hello all,
I tried a program on an array to intialise array elements from the standard input device.it is an integer array of 5 elements.but after entering the 4th element it throws a message called "Segmentation Fault" and returns to the command prompt without asking for the 5th element.

this is a network programming code to run a rock paper scissors in a client and server.
I completed it and it was working without any error. After I added the findWinner function to the server code it starts giving me segmentation fault.

I keep getting this fault on a lot of the codes I write, I'm not exactly sure why so I'd really appreciate it if someone could explain the idea to me.
For example this code

unsigned long a=0;
unsigned long b=0;
int z;

arpresolve
ARP(9) BSD Kernel Developer's Manual ARP(9)NAME
arp, arp_ifinit, arpresolve, arpintr -- externally visible ARP functions
SYNOPSIS
#include <netinet/if_inarp.h>
void
arp_ifinit(struct ifnet *ifp, struct ifaddr *ifa);
int
arpresolve(struct ifnet *ifp, struct rtentry *rt, struct mbuf *m, struct sockaddr *dst, u_char *desten);
void
arpintr();
DESCRIPTION
The arp functions provide the interface between the arp module and the network drivers which need arp functionality. Such drivers must
request the arp attribute in their "files" declaration.
arp_ifinit() Sets up the arp specific fields in ifa. Additionally, it sends out a gratuitous arp request on ifp, so that other machines are
warned that we have a (new) address and duplicate addresses can be detected.
You must call this in your drivers' ioctl function when you get a SIOCSIFADDR request with an AF_INET address family.
arpresolve() is called by network output functions to resolve an IPv4 address. If no rt is given, a new one is looked up or created. If
the passed or found rt does not contain a valid gateway link level address, a pointer to the packet in m is stored in the route
entry, possibly replacing older stored packets, and an arp request is sent instead. When an arp reply is received, the last
held packet is send. Otherwise, the looked up address is returned and written into the storage desten points to. arpresolve()
returns 1, if a valid address was stored to desten, and the packet can be sent immediately. Else a 0 is returned.
arpintr() When an arp packet is received, the network driver (class) input interrupt handler queues the packet on the arpintrq queue, and
requests an arpintr() soft interrupt callback. arpintr() dequeues the packets, performs sanity checks and calls (for IPv4 arp
packets, which are the only ones supported currently) the in_arpinput() function. in_arpinput() either generates a reply to
request packets, and adds the sender address translation to the routing table, if a matching route entry is found. If the
route entry contained a pointer to a held packet, that packet is sent.
