exit

问题 I'm confused. Supposedly, basing on man, and many other sources, like this: Return code when OS kills your process wait(&status) should make it possible for me to get the exit status or return value of a child process? Those 2 snippets of code, should allow me to see the exit value of it's child, and then print it. child process function: int childFunction(char in[],char logPath[]){ FILE *logFile= fopen( logPath, "a" ); if(logFile==NULL) return 1; int c=system(in); fclose(logFile); return(c);

问题 I am trying to modify the values of field WEORA and BSTAE in ME21n upon saving. I've written my codes in ME_PROCESS_PO_CUST BADI, in method CHECK. Below is my code. DATA: lt_data TYPE PURCHASE_ORDER_ITEMS, lo_header TYPE REF TO CL_PO_HEADER_HANDLE_MM, lt_item TYPE REF TO IF_PURCHASE_ORDER_ITEM_MM, ls_get_item TYPE MEPOITEM, ls_set_item TYPE MEPOITEM, lv_firewall TYPE abap_bool. FIELD-SYMBOLS: <fs_data> TYPE PURCHASE_ORDER_ITEM. lt_data = im_header->get_items( ). READ TABLE lt_data ASSIGNING

问题 I have a process which spawns 2 types of thread classes. One thread is responsible for consuming a job_queue (100Threads of this class are usually running). And second thread is a killing thread. I am using a result_done flag which is being set from thread2 and the issue is my threads1 wait for X seconds and then check if result_done flag is set. def run(self): while True: try: val = self.job_queue.get(True,self.maxtimeout) except: pass if self.result_done.isset(): return Now, if maxtimeout

问题 it's not recommended to exit application directly, so the point is to finish all activities so everything goes to the background and user returns to the home screen. My problem is that I have main activity, which is always launched with flags Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP and it launches another activity, where I want to place the exit button. In order to get everything to the background I have to finish both current and main activity. I though that

问题 Anywhere I've looked for this topic says (resuming): "call finish() on your activity and if you have any services running, call stopService() on them". So that I did, and as it seemed to work, I stopped worrying. Today, debugging a part of my code, I needed to add a Log line into a non-ending thread's method which I want to be executed all the app's life, basically it's something like this: final Thread buf_liberator = new Thread( new Runnable() { public void run() { while (true) { methodCall

问题 I have a Python program that I packaged with cx_freeze to make executable. The program is strictly a desktop program for data acquisition. It works fine and exits fine on every computer, but on one desktop of one of our collaborators with Windows 7 on it, it crashes only on exit (I emphasize that no pythonic errors are given. Just a low-level crash with zero information about it). Simply starting and exiting the program crashes it! I got the guy to create a memory dump for me, and he did. The

问题 I want my program to run but once esc is pressed to quit the program. The only way I can think of doing this is by doing a scanner and looking for the next line but that pauses the whole program. Maybe a key listener but how do I make it be constantly checking? And it is a GUI. Any help would be great! static Scanner sc = new Scanner(System.in); stop = sc.nextLine(); if (stop.equals(a)){ running = false; } else{ do program } 回答1: If u use a frame you can register the keys. myFrame.getRootPane

问题 anybody knows how to make event listener for flash exiting? By mean exiting is when a tag that hold the flash object is removed so that you cant see the flash anymore... Thanks 回答1: If you mean an event that gets fired upon flash destruction (web page closing, user navigating away from the page, exiting the browser or things like that), there's no help. Flash has no idea that it is about to be killed, can't signal about it, and surely can't to anything to delay/prevent the situation. If the

问题 How do I terminate the parent (main) thread from a child thread created my main? I tried System.exit(1) but it only terminate the child thread. I also tried putting a condition in main's while loop but it will obviously try to read 1 extra input before exiting. public static void main(String[] args) throws IOException { new Thread(new Runnable() { public void run() { while(true) { //meet a condition then terminate } } }).start(); while (true) { String a = input.nextLine(); //do something with
