- type – type of the handle
- handle
  - handle.fd – File descriptor referencing the semaphore object. Valid when type is ::CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_OPAQUE_FD
  - handle.win32 – Win32 handle referencing the semaphore object. Valid when type is one of the following: - ::CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_OPAQUE_WIN32 - ::CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_OPAQUE_WIN32_KMT - ::CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_D3D12_FENCE Exactly one of 'handle' and 'name' must be non-NULL. If type is ::CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_OPAQUE_WIN32_KMT then 'name' must be NULL.
    - handle.win32.handle – Valid NT handle. Must be NULL if 'name' is non-NULL
    - handle.win32.name – Name of a valid synchronization primitive. Must be NULL if 'handle' is non-NULL.
- flags – Flags reserved for the future. Must be zero.
