== Synopses

Declared in `<bslma_sequentialpool.h>`

Increase the amount of memory allocated at the specified `address` from the specified `originalNumBytes` to the maximum amount easily obtainable. Return the amount of memory available at `address` after the expansion. The behavior is undefined unless the call to this allocator that provided the `address` was performed with the `originalNumBytes`. Note that this function will not expand the memory unless there have been no allocations since the allocation for `originalNumBytes`.

Increase the amount of memory allocated at the specified `address` from the specified `originalNumBytes` to the maximum amount easily obtainable up to the specified `maxNumBytes`. Return the amount of memory available at `address` after the expansion. The behavior is undefined unless the call to this allocator that provided the `address` was performed with the `originalNumBytes` and `originalNumBytes < maxNumBytes`. Note that this function will not expand the memory unless there have been no allocations since the allocation for `originalNumBytes`.
