Practical C Programming

How it works...

Using the signal function, a signal interrupt, (SIGINT), is associated with a function called signalhandler1. That is, if the interrupt is autogenerated or is generated by the user, the sighandler1 function will be invoked. A counter, x, is initialized to 1 and a while loop is set to execute until the value of counter x becomes larger than 5. Within the while loop, the following text is displayed: Signal will be raised automatically after 5 seconds. In addition to this, the value of counter x is incremented by 1 within the while loop. A delay of 1 second is inserted in the while loop. In short, the while loop will display a text message after a gap of 1 second each. After displaying the text message 5 times, the raise function ...
