23/** @page pg_cfgldr CFGLDR - The Configuration Loader
24 *
25 * The configuration loader loads and keeps the configuration of VBox
26 * session. It will be used by VBox components to retrieve configuration
27 * values at startup and to change values if necessary.
28 *
29 * When VBox is started, it must call CFGLDRLoad to load global
30 * VBox configuration and then VM configuration.
31 *
32 * Handles then used by VBox components to retrieve configuration
33 * values. Components must query their values at startup.
34 * Configuration values can be changed only by respective
35 * component and the component must call CFGLDRSet*, to change the
36 * value in configuration file.
37 *
38 * Values are accessed only by name. It is important for components to
39 * use CFGLDRQuery* only at startup for performance reason.
40 *
41 * All CFGLDR* functions that take a CFGHANDLE or CFGNODE as their first
42 * argument return the VERR_INVALID_HANDLE status code if the argument is
43 * null handle (i.e. its value is zero).
