  Log:
  Currently, we initialize "error" to zero when it's declared, then
  we never initialize it to anything else. However, in the case that
  m_uiotombuf fails, we return error (effectively reporting success).
  
  This appears to be a relic of an older revision of this file, where
  "error" used to be doing something useful. (See revision 1.1, where
  error is used in a loop with uiomove() instead of using m_uiotomubf).
  
  So instead on unconditionally reporting success in the case there is
  a failure in m_uiotombuf, explicitly return ENOBUFS. While we are
  here, garbage collect the error variable since it's no longer required.
