Data Structures
struct	DLContext
	A Device context for Tensor and operator. More...

struct	DLDataType
	The data type the tensor can hold. More...

struct	DLTensor
	Plain C Tensor object, does not manage memory. More...

struct	DLManagedTensor
	C Tensor object, manage memory of DLTensor. This data structure is intended to facilitate the borrowing of DLTensor by another framework. It is not meant to transfer the tensor. When the borrowing framework doesn't need the tensor, it should call the deleter to notify the host that the resource is no longer needed. More...

Macros
#define	DLPACK_EXTERN_C

#define	DLPACK_VERSION 020
	The current version of dlpack. More...

#define	DLPACK_DLL
	DLPACK_DLL prefix for windows. More...

Typedefs
typedef struct DLManagedTensor	DLManagedTensor
	C Tensor object, manage memory of DLTensor. This data structure is intended to facilitate the borrowing of DLTensor by another framework. It is not meant to transfer the tensor. When the borrowing framework doesn't need the tensor, it should call the deleter to notify the host that the resource is no longer needed. More...
