OrtExternalMemoryHandle class final

\brief Base struct for imported external memory handles.

EPs derive from this struct to add EP-specific fields (e.g., CUdeviceptr for CUDA). EP is responsible for creating and releasing instances of the derived type.

Example derived type for CUDA EP: \code struct MyCudaExternalMemoryHandle : OrtExternalMemoryHandle { CUexternalMemory ext_memory; CUdeviceptr mapped_ptr; bool is_dedicated; }; \endcode

\since Version 1.24.
