I just want to know whether anyone does know about the timer control in C, the problem is that when we use any input function like getchar(),getche() or even scanf(), then if user doesn't give the input, the program is suspended for infinite time. But is there a way to get out such that you give input only within 1 min (suppose) and if user is not giving input, the program continues with the execution of program taking user input as NULL. It may be real help for online based programs in C. Like in VB we have a Timer control which does that job. Does any guy know about it or any refrence that mentions it. Thanks For Your Patient Reading.
