    Abstract: SYSTEM FOR MANAGING A PLURALITY OF SHARED INTERRUPT HANDLERS IN A LINKED-LIST DATA STRUCTURE A system is disclosed for managing a plurality of interrupt handlers in a linked-list data structure, for servicing a plurality of input/output devices sharing a common interrupt line in a microcomputer. The system provides for an orderly method to link a newly loaded interrupt handler routine into a linked-list data structure consisting of previously loaded interrupt handler routines. The system further provides for an orderly method to share a common interrupt line among a plurality of input/output devices being serviced by the interrupt handlers. The system further provides for an orderly means to unlink a particular interrupt handler routine from the linked-list data structure when a corresponding input/output device is to be deactivated. The system finds special utility in a multitasking operating system environment where input/output devices can be deactivated in a different sequence from that in which they were originally activated.
