Module nvapi_sys::handles

NVAPI Handles - These handles are retrieved from various calls and passed in to others in NvAPI These are meant to be opaque types. Do not assume they correspond to indices, HDCs, display indexes or anything else.

Most handles remain valid until a display re-configuration (display mode set) or GPU reconfiguration (going into or out of SLI modes) occurs. If NVAPI_HANDLE_INVALIDATED is received by an app, it should discard all handles, and re-enumerate them.
