I am trying to broadcast a small message on my lan using a udp broadcast
message and everytime I try the sendto method returns and errno of (13) ie.
permission denied.
anybody got any ideas on why I would get this error message.
Hi Freddy,
Did you set the SO_BROADCAST option on the socket? See
getsockopt()/setsockopt()
for details.

Did you tell setsockopt() the forth argument is one
before calling it?
{
int one=1; ← set it 1 before calling setsockopt()
if( setsockopt(socket-fd, so-level, so-broadcast, &one, sizeof(one))
failed …
…
}
A few snip of code may be helpful, …

No, I was using a zero.

thank you very much !!
