Function
GLibLogFunc
Declaration
void
(* GLogFunc) (
const gchar* log_domain,
GLogLevelFlags log_level,
const gchar* message,
gpointer user_data
)
Description [src]
Specifies the prototype of log handler functions.
The default log handler, g_log_default_handler(), automatically appends a
new-line character to message when printing it. It is advised that any
custom log handler functions behave similarly, so that logging calls in user
code do not need modifying to add a new-line character to the message if the
log handler is changed.
The log_domain parameter can be set to NULL or an empty string to use the default
application domain.
This is not used if structured logging is enabled; see Using Structured Logging.
