Resource management system having a control structure to indicate the availability of integer from an integer pool upon responsive to a request

摘要

A system and method for managing access by a user to a reusable resource. An integer pool is provided, along with program and hardware structures for obtaining an integer from the integer pool, for returning an integer to the integer pool. Responsive to the integer pool being empty, the user is waited. The integer pool includes a NEXT control structure from which a next integer is obtained for use and into which an integer is loaded upon being made available for reuse. The integer pool includes, for holding integers received from or to be provided to said NEXT control structure, (a) a LIFO stack or (b) a linked list by proxy. Reusable resources include data buffers, hardware status bits, logical connections and/or data channels.
