Re: [tuxdroid-user] Small issue with tcp/ip when disconnecting the socket

[David B. <da...@ja...>]

False alarm, it seems it's a bug in tuxgi which still tries to get the RF  
status even after it's disconnected. Sorry for the trouble :-/

But looking into this, I came up with a question about this:
  if ((send(tcp_clients_handle[i], data, sizeof(tcp_frame_t), 0)) == 0)
             tcp_remove_client(i);

Rémi got this in the past if the client was exited without telling to the  
daemon, 'send' would return 0.
Looking at the man page, I can't find how send can return 0, at least now  
in non blocking mode either it adds the data or it returns -1 as an error.  
But in blocking mode, 0 would mean that 0 bytes have been successfully  
sent. Any clarification about this?
I guess that we can change the '== 0' into '<= 0' or better '< 0' if we're  
sure 0 can't happen anymore in non-blocking mode.

Cheers,
David
