Function loadServerConfig

src/config.cpp:836–868

Load the server configuration from the specified filename. * The function appends the additional configuration directives stored * in the 'options' string to the config file before loading. * * Both filename and options can be NULL, in such a case are considered * empty. This way loadServerConfig can be used to just load a file or * just load a string. */
