NAME
	get_link - get the linked object number of the exit

PROTOTYPE
	int get_link(void)

CALLED BY
	Anybody

DESCRIPTION
	Gets the linked object number of the exit.  Certain exit types
	like ET_TWOWAY have an additional object linked to them, which is
	destroyed when they are.  This function gives the object number
	of that linked object.

	The function returns the number and not the object itself because
	the querier may not have access to the linked object, depending
	on the game's security scheme.

	This function isn't access-protected.  You should access-protect
	your version of this and all other inherited functions, including
	upgraded() and destructed().

RETURN VALUE
	The integer object number of the linked object.

ERRORS
	Usually none.
