Class OrtExternalAllocation

This class represents an arbitrary buffer of memory allocated and owned by the user. It can be either a CPU, GPU or other device memory that can be suitably represented by IntPtr. This is just a composite of the buffer related information. The memory is assumed to be pinned if necessary and usable immediately in the native code.
