You can also warp the pointer.  Something like:

#include <stdio.h>
#include <X11/Xlib.h>

int main (int argc, char *argv[] ) {
     Display *dpy;

     int screen = 1;

     dpy = XOpenDisplay(NULL);
     if (!dpy)
     {
         fprintf(stderr, "Cannot open display.\n");
         return 1;
     }

     XWarpPointer(dpy, None, RootWindow(dpy, screen), 0, 0, 0, 0, 100, 100);

     XFlush(dpy);
}
