    xref:bsl/list-054/value_type.adoc[value_type] const& value);

== Description

This method offers full guarantee of rollback in case an exception is thrown other than by the `VALUE` copy constructor or assignment operator. This method requires that the (template parameter) `VALUE` be `copy‐insertable` into this list (see {Requirements on `VALUE`}). The behavior is undefined unless `dstPosition` is an iterator in the range `[cbegin() .. cend()]endpoints included)`.

== Return Value

iterator to the newly inserted element

== Parameters

[cols="1,4"]
