30 * NOTE: Unless otherwise specified, the functions defined herein are only
31 * available in "run-time linking" mode (i.e. when the RDB_RUNTIME_LINKING
32 * option/macro is defined). In this mode, the library is not automatically
33 * loaded on application startup and must be manually loaded by calling the
34 * function riegl::rdb::library::load(). To use this mode on Linux, you must
35 * link the library "libdl" to your application.
