Detailed Description

template<>
struct fairport::disk::extended_block< ulonglong >

Unicode store version of the extended block.

Extended blocks are a way of extended the logical size of a block. It contains references to other blocks (which themselves may be extended blocks). This block can logically be thought of as the concatenation of the blocks it points to. Extended blocks begin with a header. Note the first byte of this header is the block_type - a property shared with the sub_block.
