Parameters:

data_size (size_t) – Size in bytes of the result; for ACCESSED_BY it sets how many devices (data_size // 4) are returned.
attribute (int) – A MemRangeAttribute value.
dev_ptr (uint64_t) – Start of the memory range.
count (size_t) – Size of the range in bytes.

Returns:

A list of device ordinals for ACCESSED_BY, else an int.
