A method implemented in a computer system involving a processor system includes loading a first version of a driver into memory, identifying a first endpoint set within the driver, and wrapping each endpoint in the set with a wrapper. The wrappers are registered within the operating system for calling endpoints in the first endpoint set. Subsequently, a second version of the driver is loaded into memory, and the first version is swapped with the second version. The swap process involves determining if the first version has active external calls, ceasing execution if no active calls are present, configuring the wrappers to use the second endpoint set, and initiating execution of the second version of the driver.
