You can't. You'll have to call the function each frame to move it, even if you hide it in a wrapper for the dbSync function.
The way I'd do it -
Create a class that will hold destination coords, speed and an object number, then call a 'move' member function to adjust the objects coords until it reaches the destination.
How I'd get that class created or called would depend very much on the structure of the rest of the program, but it could be something as simple as having a list of pointers to that class, and an automatic update of all objects pointed to by that list being updated in a sync wrapper.
