3.6 Making a debug node

Problem

How to create a module to debug the system I created.

Solution

Basically, printing a standard output is a way to debug your own system.

• cout << message1 << endl;

• cerr << message2 << endl;

Furthermore, when executing a created network file (called nfile.n here), use this command line, which is not from GUI of FlowDesigner ,

• ./nfile.n > log.txt
  The message (above message1) output by cout is saved in log.txt.

• ./nfile.n 2> log.txt
  The message (above message2) output by cerr is saved in log.txt.

Some nodes have a parameter DEBUG such as LocalizeMUSIC . Messages are output only when DEBUG is set a true.
