Function

Creates data of the aclDataBuffer type to describe the memory address and size.

To destroy data of the aclDataBuffer type, call aclDestroyDataBuffer.

Prototype

aclDataBuffer *aclCreateDataBuffer(void *data, size_t size)

Parameters

Parameter	Input/Output	Description
data	Input	Pointer to the address of the memory that stores data. data can be set to nullptr, indicating that an empty data type is created. In this case, the value of size must be set to 0. The memory is managed by the user. Call aclrtMalloc/aclrtFree or aclrtMallocHost/aclrtFreeHost for memory allocation/deallocation.
size	Input	Memory size, in bytes. If you need to use an empty tensor, set the minimum memory size to 1 byte during memory allocation to ensure normal running of subsequent services.
