Hi there. I'm writing a tool, which must detect is connection was terminated on remote side.
Every action on network, I'm fetching with select(). And I want in some place check if connection still active.
There are code:
-
while (1)
-
{
-
tv.tv_sec = 1;
-
tv.tv_usec = 0;
-
-
FD_ZERO (&readfds);
-
FD_SET (priv->socket, &readfds);
-
rc = select (priv->socket+1, &readfds, NULL, NULL, &tv);
-
-
if (rc<0)
-
{
-
/* error of using select() */
-
}
-
else if (rc==0)
-
{
-
/* timeout */
-
}
-
else
-
{
-
/* HERE I can read data */
-
}
-
-
/* and HERE I want to check if connection still active*/
-
}
-
How to do it in my code?
