[LC++]using readline and istream input methods?

[Julien Claassen]

Hi!
  I've got a problem, which may not be really on topic here, but I don't know
where else to ask.
  I've got a program where I use the readline library to read commands. Yet at
some points I really think it's best to use getline or cin. Yet sometimes the
following happens:
   readline prompt> input <ENTER>
  cin/getline: (some magic input I don't enter)
  I tried to empty the input buffer, but I wasn't successful. Does anyone
know:
  1. how to empty the input buffer?
  2. What this problem might be, if it isn't some backheld newline?
  Kindest regards and thanks for any help!
            Julien
