BufferManager(
char* buffer,
bsls::Types::size_type bufferSize,
bsls::Alignment::Strategy strategy = bsls::Alignment::BSLS_NATURAL);Create a buffer manager for allocating memory blocks from the specified external buffer having the specified bufferSize (in bytes). Optionally specify an alignment strategy used to align allocated memory blocks. If strategy is not specified, natural alignment is used. The behavior is undefined unless 0 < bufferSize and buffer has at least bufferSize bytes.
