Not much is known so far on what it does exactly.
All I know for sure is that it draws the specified hole ID on the pause menu map as well as on the mini-map/radar. This native also seems to change some other things related to the pause menu map's behaviour, for example: you can no longer set waypoints, the pause menu map starts up in a 'zoomed in' state. This native does not need to be executed every tick.
You need to center the minimap manually as well as change/lock it's zoom and angle in order for it to appear correctly on the minimap.
You'll also need to use the
GOLF scaleform in order to get the correct minmap border to show up.
N_0x35edd5b2e3ff01c0() to reset the map when you no longer want to display any golf holes (you still need to unlock zoom, position and angle of the radar manually after calling this).
