US 7,444,625 B2 · Concurrent code loading mechanism

Abstract

A platform independent binary object (PIBO) operable on disparate computing environments that have a selected hardware architecture without requiring rebuilding or reloading is provided. The PIBO can be parsed to generate source-code stub file. The PIBO can be loaded and linked with a cooperating computing application by an exemplary linker/loader employing the stub file. Also, the PIBO can be used in various contexts, including but not limited to, as a mechanism for dynamically linking shared objects on platforms that do not offer such native facility; in utilizing pre-written code components on platforms that otherwise would be incompatible due to a violation of platform constraints within particular code; as a mechanism for loading non object-oriented code that circumvents restrictions of multiple execution instances and repeat execution inherent in the code; and as mechanism that allows for the use of a binary object to add on functionality on a closed platform.

Claims25

Dependent claims

A computing apparatus comprising memory devices storing machine-readable instructions for loading non object-oriented code on the computing apparatus to allow multiple execution instances and repeat execution comprising, said instructions comprising:

a code library (CL) having code that is not object oriented to handle data and provide access functions to data in a manner that restricts multiple execution instances or repeat execution of the code;
a stub file, generated as a source code, cooperating with a computing application to allow the computing application to have access to the code found in the CL;
and
a dynamic linker/loader generated as source code to load an instance of the CL into a dynamically allocated memory block wherein the scope of the data variables defined in the CL is confined to the memory block;
and
a binary executable program executing on the computing apparatus, said program created by compiling the combined source code for the dynamic linker/loader, the cooperating computing application and the stub file.
