INT 2F R - InterWave Game API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running. Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes. - CLOSE GAME DEVICE AX = CD22h BX = installed program identifier DX = device handle (from AX=CD21h) Return: AL = status 00h successful FFh inavlid handle or device is not open Range: AH=CDh-ECh, selected by scanning for an available multiplex number SeeAlso: AX=CD00h"InterWave",AX=CD01h"InterWave",AX=CD02h"InterWave" SeeAlso: AX=CD05h"InterWave",AX=CD21h"InterWave",AX=CD80h"InterWave"
