INT 64 - Novell NetWare to v2.0a - LOW-LEVEL 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. Note: equivalent to INT 7A for NetWare versions through 2.0a only; later versions do not use this interrupt for IPX(Internetwork Packet Exchange) A low-level layer of Novell's NetWare networking software./SPX access, instead getting an entry point from INT 2F/AX=7A00h SeeAlso: INT 2F/AX=7A00h,INT 7A"LOW-LEVEL 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.
