BloombergLP::bdlbb::BlobUtil::copy

Copy into the specified dst starting at the specified dstOffset the specified length bytes starting at the specified srcOffset in the specified src. The behavior is undefined unless 0 <= dstOffset, 0 <= srcOffset, 0 <= length, dst || 0 == length, !dst || dstOffset <= dst->length() - length, and srcOffset <= src->length() - length. Note that this operation does not require dst to have a blob buffer factory in that it does not create or destroy blobs -- it simply copies data from src into dst, so dst must already have room for length bytes of data added at dstOffset.
