[RESOLVED] How to have time out for user input?

[ar115]

Hi,
when using std::cin >> x; for getting a variable from user
the program is halted until the user inputs something. but
i want to have a time out (e.g. 10 seconds) which after
that the program continues with a default option.
how cant I get such a functionality?

Thanks in advance

There is no way to do that with standard c++ functionality.
You will have to use OS features.

I have found a solution to it in the below page under
section "Implementing Timers Using Signals"
http://users.evtek.fi/~tk/rtp/signal....html#catching
we can use alarm() function call in unix
