Write ini file values without overwriting whole ini with boost

Question

I have function that writes one section of ini file:

boolean saveSSVar()
{
    using boost::property_tree::ptree;


    ptree pt;
    pt.put(SRV_ID, ID);
    pt.put(SRV_LOG_LEVEL, LogLevel);



    write_ini( INI_FILE_NAME, pt );

    return true;
}

Problem is that it overwrites whole file instead one section. How to solve this problem?

Just

read in original INI
update values in ptree
write resultant tree to INI

Note that not all information will roundtrip 100% (see the documentation for limitations)

Simplest way is to keep ptree as global or static.
