default_handler

Description:

public LogFunc default_handler

The default log handler set up by GLib; set_default_handler allows to install an alternate default log handler.

This is used if no log handler has been set for the particular log domain and log level combination. It outputs the message to stderr or stdout and if the log level is fatal it calls abort. It automatically prints a new-line character after the message, so one does not need to be manually included in message.

The behavior of this log handler can be influenced by a number of environment variables:

`G_MESSAGES_PREFIXED`: A :-separated list of log levels for which messages should be prefixed by the program name and PID of the aplication.
`G_MESSAGES_DEBUG`: A space-separated list of log domains for which debug and informational messages are printed. By default these messages are not printed.

stderr is used for levels g_log_level_error, g_log_level_critical, g_log_level_warning and g_log_level_message. stdout is used for the rest.

Parameters:

log_domain	the log domain of the message
log_level	the level of the message
message	the message
unused_data	data passed from log which is unused
