Logging interface.
The default logging function of the fluidsynth prints its messages to the stderr. The synthesizer uses five level of messages: FLUID_PANIC, FLUID_ERR, FLUID_WARN, FLUID_INFO, and FLUID_DBG.
A client application can install a new log function to handle the messages differently. In the following example, the application sets a callback function to display FLUID_PANIC messages in a dialog, and ignores all other messages by setting the log function to NULL:
fluid_set_log_function(FLUID_PANIC, show_dialog, (void*) root_window); fluid_set_log_function(FLUID_ERR, NULL, NULL); fluid_set_log_function(FLUID_WARN, NULL, NULL); fluid_set_log_function(FLUID_DBG, NULL, NULL);
