 Track blocks are what you place when you use the ride construction window i.e. they can be made up of multiple map elements. I know for your function its only one element but we should use track block get previous as it adds some protection. You have to pass the `x` and `y` coordinates of the start of the track block and the `map_element` of the tile. I suggest doing it like thus:

 rct_map_element* trackElement =

 The `output` is a `track_begin_end` structure. The `track_begin_end` structure should in theory give `x`, `y` coordinates of the start and end of a track block and the `map_element`'s associated with either end. In general you should only concern yourself with the begin variables.
 
 Now using `track_block_get_previous` is pretty simple. It returns `false` if it fails to find the next track block and `true` if it does find another block. On failure do not trust the contents of the `output`.
