How best to debug a module

#include "my_module.c"
#define SRC my_module

dsodbg complex_test

/******************************************
  Mosel NI Examples
  =================
    
  File dsodbg.c
  `````````````
  This program includes a module in order
  to compile it as static. This way, a
  debugger can be used with the module.
  The module name has to be replaced in the
  #include and #define lines below.
  
  Usage: dsodbg mosel_file [parameters]
  The source file is then executed with the
  provided parameters
