- don't load ze_loader.dll from file system - to perform self-open on Windows use getModuleHandleA with proper module name - don't free library loaded with getModuleHandleA - as loader may be not available during runtime teardown: - load translate handle function during global setup - load setDriverTeardown function during global teardown - when loader is not available during teardown, unset translate handle function Related-To: GSD-10147 Signed-off-by: Mateusz Jablonski <mateusz.jablonski@intel.com>
