Detailed Description

specification and retreiving of non standard options on the command line.

example:

• command line: myappli –input data.txt –val 5 –no-reco
• note: –no-reco is the negation or –reco

Source code for parsing these options:

  char* input_file  = null;
  int   value = 1;
  bool reco_mode = false;

  UOption options[] = {
    {"in","put", UOption::Arg(input_file)}, // "in" is mandatory, "put" is optionnal
    {"value","", UOption::Arg(value)},      // "value" is mandatory, no optionnal part
    {"reco","",  UOption::Arg(reco_mode)},  
    {null}  // must be NULL terminated !!
  };

  // changes the values of variables 'input_file', 'value' and 'reco_mode'
  // if the corresponding options are specified in the command line

  UConf conf(argc, argv, options);
  UAppli appli(conf);
