kill

I'm very new to c and programming and need some help. In c on linux(cygwin) I am required to remove all child processes at exit. I have looked at the other similar questions but can't get it to work. I've tried- atexit(killzombies); //in parent process void killzombies(void) { printf("works"); kill(0, SIGTERM); printf("works"); if (waitpid(-1, SIGCHLD, WNOHANG) < 0) printf("works"); } for some reason, "works" doesn't even print ever. I press ctrl + c to exit. ALSO I have tried- prctl(PR_SET_PDEATHSIG, SIGHUP); //in child process signal(SIGHUP, killMe); void killMe() { printf("works"); exit(1);

So, here is my situation : I've got a Java application that is sending arrays of data to a C++ DLL using a JNI method from a "JavaToCpp" class. Once the C++ DLL have received all the data, it begins performing several actions on it. I'm running the "JavaToCpp" class using a new thread, for my Java interface not to be frozen during the (long) (C++) procedures/subroutines. I implemented two methods to stop the working (C++) procedures/subroutines : The first one "STOP" : is creating a file which is going to be read by the C++ DLL so it can cleanly stop the running procedures/subroutines. The

If I start a forked java process from an ant script and kill the ant process, it does not kill the java process. This is the case whether running it from the IDE or from the command line. <target name="myTarget" > <java classname="path.to.MyClass" fork="yes" failonerror="true" maxmemory="128M"> <classpath refid="run" /> </java> </target> Is there a way to link these, so that killing the ant process will kill the java process? I've seen the following Q&A - but this seems to focus on how to kill the java process manually. I don't want to do this, because I have a number of other java

Is there any way to kill a running OpenCL kernel through the OpenCL API? I haven't found anything in the spec. The only solutions I could come up with are 1) periodically checking a flag in the kernel that the host writes to when it wants the kernel to stop, or 2) running the kernel in a separate process and killing the entire process. I don't think either of those are very elegant solutions, and I'm not sure #1 would even work reliably. Eric Bainville No, the OpenCL API doesn't allow to interrupt a running kernel. On some systems, a kernel running for more than a few seconds will be killed by

I have process A that starts process B. they communicate in WCF (IAsyncResult APM Pattern), A is client B is service. When Process A dies, i need to close B. I am sending process A id as arg to process b and he does: Process.GetProcessById(processId).WaitForExit(); This is working fine. My question is how to kill process b properly if process a dies ? I tried all the following: Process.GetCurrentProcess().Close(); Process.GetCurrentProcess().Dispose(); Application.Exit(); > its a guiless winform application The only thing that worked was: Process.GetCurrentProcess().Kill(); But isnt killing

I have very primitive web front-end for my C++ application. Client (web browser) is enters php site and fills form with parameters. Than (after post submit) php calls exec and application does its work. Application can work longer than minute and requires pretty large amount of RAM. Is there any possibility to detect disconnecting from client (for example closure of tab in web browser). I want to do this, because after disconnecting client will not be able to see result of computations, so I can kill application and free some RAM on server. Thanks for any help or suggestions.
