The logging of messages is handled by three dedicated macros, one for each available verbosity level (see :ref:`dds_layer_log_verbosity_level`):
- |EPROSIMA_LOG_INFO|: Logs messages with |Log::Kind::Info-api| verbosity.
- |EPROSIMA_LOG_WARNING|: Logs messages with |Log::Kind::Warning-api| verbosity.
- |EPROSIMA_LOG_ERROR|: Logs messages with |Log::Kind::Error-api| verbosity.
Said macros take exactly two arguments, a category and a message, and produce a log entry showing the message itself plus some meta information depending on the module's configuration (see :ref:`dds_layer_log_logging_spec` and :ref:`dds_layer_log_config_entry`).
.. literalinclude:: /../code/DDSCodeTester.cpp
:language: c++
:start-after: //LOG_MESSAGES
:end-before: //!--
:dedent: 4
There exist some old log macros used in previous versions: logInfo, logWarning and logError.
These macros are still available as long as user does not manually disable them by ENABLE_OLD_LOG_MACROS
CMake option or in-site macro ENABLE_OLD_LOG_MACROS_ before including Log module.
See section :ref:`old_log_macros_disable` for more information.
Warning
Note that each message level is deactivated when CMake options LOG_NO_INFO, LOG_NO_WARNING or
LOG_NO_ERROR are set to ON respectively.
For more information about how to enable and disable each individual logging macro, please refer to
:ref:`dds_layer_log_disable`.
