Abstract
The present invention is embodied in a system and method for generating and validating reference handles for consumers requiring access to resources in a multi-threaded environment of a computer system. The system of the present invention includes a resource manager having a handle administrator, a plurality of consumers, and a plurality of resources. The handle administrator includes an assignment routine, a release routine, a dereference routine, and multi-threading sub-routines enabling operation of the present invention in multi-threaded environments. The assignment routine issues new handles, the release routine releases handles that are no longer required (thus rendering the handle invalid), the dereference routine dereferences handles into a pointer to a resource, which entails verifying that the handle is valid, and the multi-threading sub-routines enable safe invalidation of handles in multi-threaded environments and also ensure consistent use of pertinent values, such as array pointers and array sizes during operation of the expansion and contraction sub-routines.
