Use the function:

itr = mylist.insert_after(Itr, value)

It will insert the value after the position pointed by itr.

that's what list::insert does. Just increment your iterator before inserting your value:

if (someIterator != someList.end()) {
    someIterator++;
}
someList.insert(someIterator, someValue);
