I tried clearing m_variables map by doing m_variables.clear() (which is a member of configuration class) - but after that some variables from the configuration file wont be read. If I constrct new variables map each time I want to reload configuration file it works just fine. Is there any other way around this problem? I would like to be able to use one variables map so that I could use functions read_command_line() and read_config_file() which are both members of configuration class. Many thanks!

Hello

I want to implement function in my application which would allow me to reload the configuration file.

At the moment I have all neccessary program_options objects inside a configuration class, and when I do:

bool configuration::reload_config_file(std::string filename) { try { std::ifstream ifs(filename.c_str()); if (!ifs.is_open()) return false;

boost::program_options::store(boost::program_options::parse_config_file(ifs, m_config), m_variables); boost::program_options::notify(m_variables);

ifs.close(); } catch (std::exception &e) { return false; } return true; }

The options will stay the same although the configuration file is different. Should I somehow clear the m_variables object?

Many thanks in advance!
