www.facebook.com
www.google.com
the output should be:
www.google.com x2
www.facebook.com x1
However I cannot get this to work at the moment, can somebody please tell me what is wrong with my code:

ne_addr_resolve
NE_ADDR_RESOLVE(3) neon API reference NE_ADDR_RESOLVE(3)NAME
ne_addr_resolve, ne_addr_result, ne_addr_first, ne_addr_next, ne_addr_error, ne_addr_destroy - functions to resolve hostnames to addresses
SYNOPSIS
#include <ne_socket.h>
ne_sock_addr *ne_addr_resolve(const char *hostname, int flags);
int ne_addr_result(const ne_sock_addr *addr);
const ne_inet_addr *ne_addr_first(ne_sock_addr *addr);
const ne_inet_addr *ne_addr_next(ne_sock_addr *addr);
char *ne_addr_error(const ne_sock_addr *addr, char *buffer, size_t bufsiz);
void ne_addr_destroy(ne_sock_addr *addr);
DESCRIPTION
The ne_addr_resolve function resolves the given hostname, returning an ne_sock_addr object representing the address (or addresses)
associated with the hostname. The flags parameter is currently unused, and must be passed as 0.
The hostname passed to ne_addr_resolve can be a DNS hostname (e.g. "www.example.com") or an IPv4 dotted quad (e.g. "192.0.34.72"); or, on
systems which support IPv6, an IPv6 hex address, which may be enclosed in brackets, e.g. "[::1]".
To determine whether the hostname was successfully resolved, the ne_addr_result function is used, which returns non-zero if an error
occurred. If an error did occur, the ne_addr_error function can be used, which will copy the error string into a given buffer (of size
bufsiz).
The functions ne_addr_first and ne_addr_next are used to retrieve the Internet addresses associated with an address object which has been
successfully resolved. ne_addr_first returns the first address; ne_addr_next returns the next address after the most recent call to
ne_addr_next or ne_addr_first, or NULL if there are no more addresses. The ne_inet_addr pointer returned by these functions can be passed
to ne_sock_connect to connect a socket.
After the address object has been used, it should be destroyed using ne_addr_destroy.
RETURN VALUE
ne_addr_resolve returns a pointer to an address object, and never NULL. ne_addr_error returns the buffer parameter .
EXAMPLES
The code below prints out the set of addresses associated with the hostname www.google.com.
ne_sock_addr *addr;
char buf[256];
addr = ne_addr_resolve("www.google.com", 0);
if (ne_addr_result(addr)) {
printf("Could not resolve www.google.com: %s
",
ne_addr_error(addr, buf, sizeof buf));
} else {
const ne_inet_addr *ia;
printf("www.google.com:");
for (ia = ne_addr_first(addr); ia != NULL; ia = ne_addr_next(addr)) {
printf(" %s", ne_iaddr_print(ia, buf, sizeof buf));
}
putchar('
');
}
ne_addr_destroy(addr);
