1. A method in a computer system for emulating the sharing of a resource between a first program and a second program running on an operating system that cannot allocate the resource so that it is accessible by every program executing in conjunction with the operating system, the method being performed under the control of the operating system, the method comprising:

  • (a) intercepting a transfer message directed by the first program to the second program as an attempt by the first program to share an original resource being used by the first program with the second program, the transfer message having a reference to the original resource;

    (b) creating a duplicate resource being a separate copy of the original resource and accessible to the second program;

    (c) substituting the reference to the original resource in the transfer message with a reference to the duplicate resource;

    (d) storing the references to the original resource and duplicate resource; and

    (e) forwarding the transfer message with the reference to the created duplicate resource to the second program so that the second program can access the provided duplicate resource to emulate the sharing of the original resource with the second program.
