This extension defines a feature, LV2_Log_Log, which allows plugins to print +messages to logs implemented by the host with an API much like the standard C +printf functions. This allows, for example, plugin logs to be nicely presented +to the user in a graphical user interface.

+ +

Different log levels (e.g. error or information) are +defined by URI and passed as an LV2_URID. Thus, the possible number of log +levels is unlimited, but implementations SHOULD use the levels defined in this +extension unless they have a special reason to do otherwise.
