Hello everybody,
Could U help me please it's very important of course :(
I'm doing (trying exactly) a little client/serveur tcp programm.
the skeleton is classic (from server side)
main()
{
fd_set readfds, rmask;
struct timeval tv;
int sd;
...
sd = create_socket();
...
while(1)
{
FD_ZERO(&rmask);
FD_SET(sd, &rmask);
readfds = rmask;
tv.tv_sec=5;
tv.tv_usec=0;
if ( select(FD_SETSIZE, &readfds, NULL, NULL, &tv) )
{
if (errno!=EINTR)
{
/* socket gets something ! */
if (FD_ISSET(sd ,&readfds))
{
// goto child
fork();
...
}
}
}
Everything works except the famous FD_SETSIZE (yes I use select()) limit to 64
Now If I run a sample client test with a loop which try to connect 64
times to my server,
it works... but with FD_SETSIZE limit, my server will hang after 64 fork.
Right, but now, always on client side :
If I try a loop with 32 connection, it's ok.
then I stop all my clients connexion - the children on server side die (ok)
If I try to connect again 32 times with my client by running my test
program again...
I meet again the FD_SETSIZE limit !!!
I suppose I've forgotten something on server side but where ???
please help me
