I have a TF2 server and if TF2 gets updated while I’m away, server will output:
Your server is out of date. Please update and restart.
How could I observer/read the output with C++?
The idea is:
1. if (output == "Your server is out of date. Please update and restart.")
2. kill the application
3. run update.bat
4. start observing again
Is my idea possible?
That’s basically a watchdog.
A solution can be done using piping:
Pipe your server output to standard input from your C++ application (reading it with cin will do). For example, if your TF2 server is tf2.exe and your C++ app is cpp.exe:
You will need to execute this command again everytime you’re restarting the server (which involves exiting the C++ app after doing so since it will be re-run by the command).
