exit

In my Android app developed with libGDX I use Gdx.app.exit() when the user tries to exit the game. This closes the game, but when the user restarts the app all the Textures are scrambled (beyond the point of using the app). I noticed that if I force close the app from a task-manager, then it will restart properly. Why does it happen? You have rediscovered the mismatch between the lifetime of Java objects (tied to the life of the application process) and the lifetime of texture objects (tied to the life of the OpenGL context which is tied to the visibility of the Activity). On app "exit", just

I know the differences between the two . One notable thing is that abort() sends SIGABRT signal, so it may be relevant when your software relies on them. But for a typical application exit() seems to be more safe version of abort()...? Are there any other concerns to use abort() instead of exit()? Using abort will dump core, if the user has core dumps enabled. So as a rule of thumb, I'd use abort if you're so unsure about what's gone wrong that the only way to get useful information about it is by analysing a core dump. If you can safely exit from any given point, and don't need the core dump,

I have a Docker container running in a host of 1G RAM (there are also other containers running in the same host). The application in this Docker container will decode some images, which may consume memory a lot. From time to time, this container will exit. I doubt it is due to out of memory but not very sure. I need a method to find the root cause. So is there any way to know what happened for this container's death? Others have mentioned docker logs $container_id to view the output of the application. This would always be my first thing to check. Next, you can run a docker inspect $container

I want to write code like this: command="some command" safeRunCommand $command safeRunCommand() { cmnd=$1 $($cmnd) if [ $? != 0 ]; then printf "Error when executing command: '$command'" exit $ERROR_CODE fi } But this code does not working the way I want. Where I made mistake? havexz Below is the fixed code: #!/bin/ksh safeRunCommand() { typeset cmnd="$*" typeset ret_code echo cmnd=$cmnd eval $cmnd ret_code=$? if [ $ret_code != 0 ]; then printf "Error : [%d] when executing command: '$cmnd'" $ret_code exit $ret_code fi } command="ls -l | grep p" safeRunCommand "$command" Now if you look into

I'm looking for a good way to tell my Cocoa application to quit itself. Rest assured that this will not be used for production code. I'm just looking for an easy way to run one test and then close the application during debugging. I have found that exit(0); will close the app, but it bypasses all of the normal application exit procedures, and I would like to keep all of them in place. Essentially I want things to work as if a user pulled "Quit" from the menu, but I want it to happen automatically after I have finished with my test. My code currently looks like this: #if (SUPERFANCY_TESTING

How would you exit out of a function if a condition is true without killing the whole script, just return back to before you called the function. Example # Start script Do scripty stuff here Ok now lets call FUNCT FUNCT Here is A to come back to function FUNCT { if [ blah is false ]; then exit the function and go up to A else keep running the function fi } Use: return [n] From help return return : return [n] Return from a shell function. Causes a function or sourced script to exit with the return value specified by N. If N is omitted, the return status is that of the last command executed

I'm building a Shell Script that has a if function like this one: if jarsigner -verbose -keystore $keyst -keystore $pass $jar_file $kalias then echo $jar_file signed sucessfully else echo ERROR: Failed to sign $jar_file. Please recheck the variables fi ... I want the execution of the script to finish after displaying the error message. How I can do this? Byron Whitlock Are you looking for exit ? This is the best bash guide around. http://tldp.org/LDP/abs/html/ In context: if jarsigner -verbose -keystore $keyst -keystore $pass $jar_file $kalias then echo $jar_file signed sucessfully else echo

What's the difference? Which is preferred, or when should I use each one respectively? Alok Save exit(1) (usually) indicates unsuccessful termination. However, its usage is non-portable. For example, on OpenVMS , exit(1) actually indicates success. Only EXIT_FAILURE is the standard value for returning unsuccessful termination, but 1 is used for the same in many implementations. So to summarize: If you want to write perfectly portable code use, EXIT_FAILURE for failure case. While, You can use either exit(0) or EXIT_SUCCESS for success case. Note that, EXIT_SUCCESS or 0 are both same. Reference
