Function

GLiblog

Declaration

void
g_log (
  const gchar* log_domain,
  GLogLevelFlags log_level,
  const gchar* format,
  ...
)

Description

Logs an error or debugging message.

If the log level has been set as fatal, G_BREAKPOINT() is called to terminate the program. See the documentation for G_BREAKPOINT() for details of the debugging options this provides.

If g_log_default_handler() is used as the log handler function, a new-line character will automatically be appended to @…, and need not be entered manually.

If [structured logging is enabled][using-structured-logging] this will output via the structured log writer function (see g_log_set_writer_func()).
