GM_SetAreaFeatureDrawStyle

Sets the style and font to use for drawing the given area object. Pass NULL for the area style to reset the drawing style to the default style for the classification of the area.

Typically, when modifying the drawing style of an area you'll want to call GM_GetAreaFeature to get the current drawing style, then copy the mAreaStyle member of the GM_AreaFeature_t and just change what you need, then pass your copy in to this function.

const GM_AreaStyle_t*   aAreaStyle          // New style to use for area
