int CUDA_EXTERNAL_MEMORY_HANDLE_DESC::fd

File descriptor referencing the memory object. Valid when type is CU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_FD

void* CUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle

Valid NT handle. Must be NULL if 'name' is non-NULL

unsigned long long CUDA_EXTERNAL_MEMORY_HANDLE_DESC::size

Size of the memory allocation

CUexternalMemoryHandleType CUDA_EXTERNAL_MEMORY_HANDLE_DESC::type

Type of the handle

struct { ... } CUDA_EXTERNAL_MEMORY_HANDLE_DESC::win32

Win32 handle referencing the semaphore object. Valid when type is one of the following:

• CU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32
• CU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_KMT
• CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP
• CU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE 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.
