Abstract

A method is disclosed for controlling access to a shared resource which can receive concurrent access requests for any shared resource from different application threads. This resource access manager can manage thread synchronization mechanisms for each of the shared resources to eliminate the possibility of data corruption or deadlock when multiple accesses to the same shared resource are performed. Further, a method for creating a multiple resource manager which controls access to many shared resources is disclosed. The multiple resource manager allows threads to request access to resources via name, number or other identifier, and routes these accesses to the resource access manager associated with the shared resource. The code for the resource access manager and multiple resource manager may be implemented as a class within a library of classes to allow programmers to use the class without having to know all the details of its inner workings.
