How to implement timeout for getline()?
c++, centos, gcc
Solution
How about:
/* Wait 5 seconds. */
alarm(5);
/* getline */
/* Cancel alarm. */
alarm(0);
Alternatively you could use `setitimer`.
As R. Martinho Fernandes requested:
The function `alarm` arranges for the current process to receive a SIGALRM in 5 seconds from its call. The default action for a `SIGALRM` si to terminate the process abnormally. Calling `alarm(0)` disables the timer.
Problem
I want to read a string from command line through `getline()` in c++. For that I want to add a timer of `5` sec. If no string read, then the program will terminate. How can I do this?
