Question

Here i have one function which is listen mode. this function listing something which i got form some device.

Here when my function is in listen mode that time i want to create timeout. if i will not get any response from particular device than i want o exit from this function and have to notify.

if during this timeout period if i will get response from device than i have to continue with work and stop this timeout and there is no limits to complete this work in any time duration.

So how can i implement this thing for a function.

Any body please can me help me to implement this thing with timeout functionality.

Take a look at man 2 alarm. You can set or disable signals which will be sent to your application after a certain time period elapses.
