Thread: timegap between execution of functions

hi,

i want my code to execute a set of functions keeping a certain time gap between the executions. how do i do that?

thanks

what compiler and operating systems. *nix uses sleep(int seconds) and MS-Windows uses Sleep(long milliseconds) (note spelling differences). MS-DOS Borland compilers like TurboC uses delay(). I don't know about other operating systems.

actually i want to disply an object moving down on a xwindow. so i used the following method. but now i want to display an arbitrary numer of such objects dropping at different times, different different x cooordinates.

Code:

while(j<height_window)
	{
		XSetForeground(disp,gc,BlackPixel(disp,DefaultScreen(disp)));
		XFillArc(disp, win, gc, 300-(30/2), j-(30/2), 30, 30, 0, 180*64);
		XFlush(disp);
		usleep(20000);
		c1++;
		if(c1>20)
		{			
		j=j+10;
		XSetForeground(disp,gc,WhitePixel(disp,DefaultScreen(disp)));
		XFillArc(disp, win, gc, 300-(30/2), j-10-(30/2), 30, 30, 0, 180*64);
	}

so this is the the whole picture

the
part

Code:

if(c1>20)
{

shouldn't be thr.

You could have just pressed the <Edit> button and removed it.

I suppose you might have to implement threads to do that where each object type is in its own thread.

how do i do that in c

depends on the os. you posted usleep() so I think you are using some version of *nix.

here is a tutorial
