In some cases * general information about your source file is emitted as well. Reports * are emitted in the current output buffer, but LibTidy users will probably * prefer to hook into a callback in order to take advantage of the data * that are available in a more flexible way. * * - Dialogue, consisting of footnotes related to your source file, and of * general information that's not related to your source file in particular. * This is also written to the current output buffer when appropriate, and * available via callbacks. * * Report information typically takes the form of a warning, an error, info, * etc., and the output routines keep track of the count of these. * * The preferred way of handling Tidy diagnostics output is either * - define a new output sink, or * - use a message filter callback routine. * * @author HTACG, et al (consult git log) * * @copyright * Copyright (c) 1998-2017 World Wide Web Consortium (Massachusetts * Institute of Technology, European Research Consortium for Informatics * and Mathematics, Keio University) and HTACG. * @par * All Rights Reserved. * @par * See `tidy.h` for the complete license. * * @date Additional updates: consult git log * ******************************************************************************/ #include "forward.h" /** @addtogroup internal_api */ /** @{ */ /***************************************************************************//** ** @defgroup message_releaseinfo Tidy Release Information ** ** These functions return information about the current release version date ** and version number.
