Good morning.
Suppose we have a very little data structure - in kernel space - :
typedef struct
{
__u32 saddr, daddr;
__u16 sport, dport;
short int valid;
} net_quadruplet;
net_quadruplet get_quad_from_skb(const struct sk_buff* skb)
{
net_quadruplet netquad;
memset(&netquad, 0, sizeof(net_quadruplet));
netquad.valid = 1;
...
return netquad;
}
Is it perfectly legal?
Would it be more efficient
int get_quad_from_skb(const struct sk_buff* skb, net_quadruplet* nquad)
{
int return_value = 0;
/* modify nquad
.....
*/
return return_value;
}
?
Thank you very much for your attention.
Giacomo
