sleep

问题 script A (insert (current-time-string)) (sleep-for 5) (insert (current-time-string)) M-x eval-buffer , two time strings are inserted with 5 secs apart script B some comint code (that add hook, and start process) (sleep-for 60) ;delay a bit for process to finish (insert "ZZZ") M-x eval-buffer , "ZZZ" is inserted right away, without any time delay what might have happened? btw, it's Emacs 23.2 on Win XP 回答1: If all you want to do is to wait for a process to finish, you should probably not use

问题 When scraping multiple websites in a loop, I notice there is a rather large difference in speed between, sleep(10) response = requests.get(url) and, response = requests.get(url, timeout=10) That is, timeout is much faster. Moreover, for both set-ups I expected a scraping duration of at least 10 seconds per page before requesting the next page, but this is not the case. Why is there such a difference in speed? Why is the scraping duration per page less than 10 seconds? I now use

问题 void keyPress(unsigned char key,int x,int y){ int i; switch(key){ case 'f': i = 3; while(i--){ x_pos += 3; sleep(100); glutPostRedisplay(); } } } Above is the code snippet written in C++ using GLUT library in Windows 7. This function takes a character key and mouse co-ordinates x,y and performs translation along x-direction in 3 successive steps on pressing f character. Between each step the program should sleep for 100 ms. We want to move a robot, and pause successively when he moves forward

问题 In a c++ program run on Win7, is there a way to fake a mouse movement or something like that, just to keep the screen saver from starting and the system from going to sleep? I'm looking for the minimal approach and I prefer not to use .NET. Thanks, -nuun 回答1: Don't mess with the screensaver settings, use SetThreadExecutionState. This is the API for informing windows on the fact that your application is active: Enables an application to inform the system that it is in use, thereby preventing

问题 I just want to set a node to sleep in ns-2 and i have searched in protocols and i found a lot of objects and functions about sleep but i couldn't use them in other protocols to set a node to sleep. when i use them i get Segmentation fault or Floating point and i know what these errors mean but i can't find a way to solve them. Like when i use sleep() function from SMAC. I have searched in google and after a week i still didn't find any solution...! could you guys please help me here...? 回答1:

问题 I have a very simple class that sets and cancels an AlarmManager to broadcast intents: public class MyIntentsAlarm { public void setAlarm(Context context){ AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); Intent i = new Intent("MY_ACTION"); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); am.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),5*60*1000L, pi); } public void cancelAlarm(Context context){ Intent intent = new

问题 I enjoy making little games in C++ and Java, but something has always bothered me, and I've never quite understood how to remedy it. Sleep in C++ and Java only works in milliseconds. Meaning that if you do startTime=clock(); -------Execute everything in that frame----- endTime=clock(); sleep(x-(endTime-startTime)); if x is 16 you get 62.5 frames per second if x is 17 you get 58.8 frames per second Neither of which is that perfect 60 to fit a monitor's refresh rate. But I've noticed some games
