[#bsl-deque-0c-max_size]
= xref:bsl.adoc[bsl]::xref:bsl/deque-0c.adoc[deque]::max_size
:relfileprefix: ../../
:mrdocs:

Return the maximum possible size of this deque. Note that this is a theoretical maximum (such as the maximum value that can be held by `size_type`). Also note that any request to create or enlarge a deque to a size greater than `max_size()` is guaranteed to raise a `bsl::length_error` exception.
