std::regex_search and his std::smatch as return value in template

Take a look on my code and tell me how to do this proper way. First of all this is part of my config manager class. Generally i want to use read function only with three main types of data int, float, string (maybe bool in futhure).

template<typename T>
T Read(const std::string& name)
{
    T retVal;
    std::string buffer;

    while(std::getline(m_hFile, buffer))
    {
        if(strstr(buffer.c_str(), name.c_str()))
        {                
            std::smatch match;
            const std::regex regex_patern("=\"(.*)\"");
            std::regex_search(buffer, match, regex_patern);
            retVal = ????
            break;
        }
    }

    return retVal;
}

How can i cast this std::smatch to get it work? What should i do there? I dont really have idea. Any tips or code snippets are welcome.
