clean_up_memory()

void oomph::TerminateHelper::clean_up_memory

(

)

Clean up function that deletes anything dynamically allocated in this namespace

    {
      // If it's a null pointer
      if (Exception_stringstream_pt != 0)
      {
        // Delete it
        delete Exception_stringstream_pt;
 
        // Make it a null pointer
        Exception_stringstream_pt = 0;
      }
    } // End of clean_up_memory
