:mrdocs:

Copy the specified `length` bytes starting at the specified `position` in the specified `srcBlob` to the specified `dstBuffer`. The behavior of this function is undefined unless `0 <= length`, `0 <= position`, `position <= srcBlob.totalSize() ‐ length`, and `dstBuffer` has room for `length` bytes. Note that this function does _not_ set `dstBuffer[length]` to 0.
