The answer to the original question “what happens to a detached thread when main() exits” is: It continues running (because the standard doesn’t say it is stopped), and that’s well-defined, as long as it touches neither (automatic|thread_local) variables of other threads nor static objects. This appears to be allowed to allow thread managers as static … Read more
To exit a script you can use, import sys sys.exit() You can also provide an exit status value, usually an integer. import sys sys.exit(0) Exits with zero, which is generally interpreted as success. Non-zero codes are usually treated as errors. The default is to exit with zero. import sys sys.exit(“aa! errors!”) Prints “aa! errors!” and … Read more
System.exit() can be used to run shutdown hooks before the program quits. This is a convenient way to handle shutdown in bigger programs, where all parts of the program can’t (and shouldn’t) be aware of each other. Then, if someone wants to quit, he can simply call System.exit(), and the shutdown hooks (if properly set … Read more
Android’s design does not favor exiting an application by choice, but rather manages it by the OS. You can bring up the Home application by its corresponding Intent: Intent intent = new Intent(Intent.ACTION_MAIN); intent.addCategory(Intent.CATEGORY_HOME); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent);
If you are using Visual Studio and you are starting the console application out of the IDE: pressing CTRL-F5 (start without debugging) will start the application and keep the console window open until you press any key.
“exit” functions usually quit the program or script along with an error message as paramete. For example die(…) in php die(“sorry my fault, didn’t mean to but now I am in byte nirvana”) The equivalent in JS is to signal an error with the throw keyword like this: throw new Error(); You can easily test … Read more
Actually, there is a difference, but it’s subtle. It has more implications for C++, but the differences are important. When I call return in main(), destructors will be called for my locally scoped objects. If I call exit(), no destructor will be called for my locally scoped objects! Re-read that. exit() does not return. That … Read more
With set +e. Yeah, it’s backward that you enable shell options with set – and disable them with set +. Historical raisins, donchanow.
To exit Pry unconditionally, type exit-program Edit from @Nick’s comment: Also works: !!!
From MSDN: Application.Exit Informs all message pumps that they must terminate, and then closes all application windows after the messages have been processed. This is the code to use if you are have called Application.Run (WinForms applications), this method stops all running message loops on all threads and closes all windows of the application. Environment.Exit … Read more
