I am using the select function and I am selecting between a fd_set that contains my socket and a time interval. FD_SET(udpsock, &mySet); select(1, &mySet , NULL, NULL, &time); and when the time is up I want to run some set of code, and when the udpSock is writen to I want to run some other set of code. I know for the udp sock it is if(FD_ISSET(udpSock, &mySet)) { //code for udpSock } but I do not know what to do for when the time is up. Thanks for all help Joe Madden

If the select statment timed out, then the fd_set shouldn''t have udpsock set. This sounds like the perfect time to use the "else" keyword.

thanks I''ll try that, but if the time is set at 15 seconds
and I use else,

so if(FD_ISSET(...))
{
}
else
{
//rest code
}

will the else statement run at that 15 sec interval
Thats what I am confused about

Thanks again
Joe
