Release allocated memory while retaining this pool's typical internal buffers.

== Synopsis

Declared in `<bdlma_bufferedsequentialpool.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
void
rewind();

== Description

Release all memory allocated through this pool and return to the underlying allocator _only_ memory that was allocated outside of the typical internal buffer growth of this pool (i.e., large blocks). All retained memory will be used to satisfy subsequent allocations. The effect of subsequently ‐ to this invokation of `rewind` ‐ using a pointer obtained from this object prior to this call to `rewind` is undefined.
