Insert value if an equivalent key is not already present.
Declared in <bslstl_set.h>
pair<set<KEY, COMPARATOR, ALLOCATOR>::iterator, bool>
insert(value_type const& value);Return a pair whose first member is an iterator referring to the (possibly newly inserted) value_type object in this set that is equivalent to value, and whose second member is true if a new value was inserted, and false if the key was already present. This method requires that the (template parameter) type KEY be copy-insertable into this set (see {Requirements on KEY}).
