Declared in `<bdlma_buffermanager.h>`

Create a buffer manager for allocating memory blocks. Optionally specify an alignment `strategy` used to align allocated memory blocks. If `strategy` is not specified, natural alignment is used. A default constructed buffer manager is unable to allocate any memory until an external buffer is provided by calling the `replaceBuffer` method.

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.
