Description

Copies memory in scenarios where the base address is a level-2 pointer and an address offset exists. This API is asynchronous.

Prototype

aclError aclrtMemcpyAsyncWithOffset(void **dst, size_t destMax, size_t dstDataOffset, const void **src, size_t count, size_t srcDataOffset, aclrtMemcpyKind kind, aclrtStream stream)

Parameters

Parameter	Input/Output	Description
dst	Input	Pointer to the destination memory address.
destMax	Input	Memory size in bytes in the destination address
dstDataOffset	Input	Offset of the destination memory address.
src	Input	Pointer to the source memory address.
count	Input	Size in bytes to copy.
srcDataOffset	Input	Offset of the source memory address.
kind	Input	Memory copy type. Currently, only ACL_MEMCPY_INNER_DEVICE_TO_DEVICE is supported, indicating memory copy within a device.
stream	Input	Stream for executing the memory copy task.

Returns

0 on success; else, failure. For details, see aclError.
