memcpy_opt()

DW_API_PUBLIC void * memcpy_opt	(	void *__restrict const	destination,
		const void *__restrict const	source,
		size_t const	num
	)

Memory copy of virtual process memory.

This subroutine shall call std::memcpy() for x86_64, and custom optimized implementation for aarch64. As in standard memcpy call destination and source memory blocks should not overlap.

NOTE: This function shall be used only if the source address belongs to a CUDA Pinned Host memory region. If either destination or source is an invalid or null pointer, the behavior is undefined, even if count is zero. Please check std::memcpy() documentation for details.

Note

The method has been deprecated and replaced by standard std::memcpy() implementation due to safety concerns.

Parameters

[out]	destination	pointer to destination memory into which num bytes will be copied from source
[in]	source	pointer to source memory which will be copied destination
[in]	num	number of bytes to copy

Returns

pointer to destination
