Memory copy of virtual process memory.
This subroutine 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: only use this function 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.
| [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 |
