abort

Sometimes after calling a function (which takes some 30 odd minutes to finish), you realize that you did something wrong and want to stop the program . How do you do that in MATLAB? What I do is shutdown MATLAB completely and restart . I think there would be a way to abort the execution of the function instead. Anybody know what that is? Hitting Ctrl + C usually does the trick, although sometimes it has been known to run into snags . 来源： https://stackoverflow.com/questions/1500314/how-to-abort-a-running-program-in-matlab

I need to call a library function that sometimes won't terminate within a given time, unfortunately. Is there a way to call the function but abort it if it doesn't terminate within n seconds? I cannot modify the function, so I cannot put the abort condition into it directly. I have to add a timeout to the function externally . Is it maybe a possible solution to start it as a (boost) thread, which I can then terminate after a certain time? Would something like that work? I actually believe the function is not thread-safe, but that wouldn't matter if I run it as the only single thread, right?

I have this code: void drawInitialNim(int num1, int num2, int num3) { int board[2][50]; //make an array with 3 columns int i; // i, j, k are loop counters int j; int k; for(i=0;i<num1+1;i++) //fill the array with rocks, or 'O' board[0][i] = 'O'; //for example, if num1 is 5, fill the first row with 5 rocks for (i=0; i<num2+1; i++) board[1][i] = 'O'; for (i=0; i<num3+1; i++) board[2][i] = 'O'; for (j=0; j<2;j++) { //print the array for (k=0; k<50;k++) { printf("%d",board[j][k]); } } return; } int main() { int numRock1,numRock2,numRock3; numRock1 = 0; numRock2 = 0; numRock3 = 0; printf("Welcome

I have a thread which contains execution of an IronPython script. For some reason I may need to stop this thread at any time, including script execution. How to achieve this? The first idea is Thread.Abort() , but it's known to be evil... Tudor Well from you question and subsequent comments I can suggest you two options, with some additional "warnings": If your thread loops executing something on each iteration, you can set a volatile boolean flag such that it exits after finishing the current iteration (pseudocode because I'm not familiar with python): while shouldExit = false // do stuff

In C and C++, what is the difference between exit() and abort() ? I am trying to end my program after an error (not an exception). abort() exits your program without calling functions registered using atexit() first, and without calling objects' destructors first. exit() does both before exiting your program. It does not call destructors for automatic objects though. So A a; void test() { static A b; A c; exit(0); } Will destruct a and b properly, but will not call destructors of c . abort() wouldn't call destructors of neither objects. As this is unfortunate, the C++ Standard describes an

I would like to force a core dump at a specific location in my C++ application. I know I can do it by doing something like: int * crash = NULL; *crash = 1; But I would like to know if there is a cleaner way? I am using Linux by the way. paxdiablo Raising of signal number 6 ( SIGABRT in Linux) is one way to do it (though keep in mind that SIGABRT is not required to be 6 in all POSIX implementations so you may want to use the SIGABRT value itself if this is anything other than quick'n'dirty debug code). #include <signal.h> : : : raise (SIGABRT); Calling abort() will also cause a core dump, and
