/* Logging levels */ /*
Logging Levels
==============
A log level will automatically include the lower levels. For example, verbose logging will enable everything. The warning log level will only include warnings
and errors, but will ignore informational and verbose logging. If you only want to handle a specific log level, implement a custom log callback (see
ma_context_init() for details) and interrogate the `logLevel` parameter.
By default the log level will be set to MA_LOG_LEVEL_ERROR, but you can change this by defining MA_LOG_LEVEL before the implementation of miniaudio.
MA_LOG_LEVEL_VERBOSE
Mainly intended for debugging. This will enable all log levels and can be triggered from within the data callback so care must be taken when enabling this
in production environments.
MA_LOG_LEVEL_INFO
Informational logging. Useful for debugging. This will also enable warning and error logs. This will never be called from within the data callback.
MA_LOG_LEVEL_WARNING
Warnings. You should enable this in you development builds and action them when encounted. This will also enable error logs. These logs usually indicate a
potential problem or misconfiguration, but still allow you to keep running. This will never be called from within the data callback.
MA_LOG_LEVEL_ERROR
Error logging. This will be fired when an operation fails and is subsequently aborted. This can be fired from within the data callback, in which case the
device will be stopped. You should always have this log level enabled.
