:mrdocs:

Set the `guardSize` attribute of this object to the specified `value` (in bytes). Return a non‐`const` reference to this object (see also {Fluent Interface}). `e_UNSET_GUARD_SIZE == guardSize` is intended to indicate that the default value as defined by the platform is to be used. This default value is typically the size of one or two pages (see `bslmt_configuration`). The behavior is undefined unless `e_UNSET_GUARD_SIZE == guardSize` or `guardSize >= 0`.
