Writing Safe Code with SCL

To make sure your code is as safe as possible, you should wrap your operations that use SCL within try-catch block.

try {
  scl::config_file file("example.config", scl::config_file::READ);
  int i = file.get<int>("integer value");

  //do something with int here...


  //file implicitly closed by destructor
} catch (std::exception& e) {
  //handle the issue opening the file here
  std::cerr << "Error: Exception thrown! Details : " << e.what() << '\n';
}
