FJ_ARE_STRUCTURE - delete a proximity trigger?

[subtledoctor]

I am looking at this function and it says:

Quote

• STR_VAR fj_structure_type to the type of area structure to be added (actor, region, spawn, entrance, container, itm, ambient, variable, door, animation, bitmask, songs, interrupts, note or projectile);
• INT_VAR fj_delete_mode to the index of the structure to be deleted (if deleting rather than adding a new structure)

I want to delete a proximity trigger form a map. Trigger #17. But, I do not know what kind of "structure" that is for purposes of this function. The way Near Infinity displays .ARE files does not seem to match up with the categories that this function expects. Can anyone help me translate between them?

As far as I know, triggers are regions with their short field at 0x2 set to 0. The value  of 1 is for stuff that puts a ? on your cursor, and when set to 2 it's just an area travel region.

Yeah, proximity triggers are regions.
