''' This script shows three method to terminate your application. `terminate_programmatically()`
|
||
|
shows the recommended way, which kills the child by sending the application specific exit command.
|
||
|
After that waiting for the terminaton is recommended.
|
||
|
`terminate_eof()` shows how to terminate child program by sending EOF character. Some program can be
|
||
|
terminated by sending EOF character. Waiting for the terminaton is recommended in this case too.
|
||
|
`terminate_terminate()` shows how to terminate child program by sending kill signal. Some
|
||
|
application requires sending SIGTERM to kill the child process. `terminate()` call `kill()`
|
||
|
function, which sends SIGTERM to child process. Waiting for the terminaton is not required
|
||
|
explicitly in this case. The wait is included in `terminate()` function.
