Function Documentation

int G_fatal_error	(	const char *	msg,
			...
	)

Print a fatal error message to stderr.

The output format depends on environment variable GRASS_MESSAGE_FORMAT

By default, the message is handled by an internal routine which prints the message to the screen. Using G_set_error_routine() the programmer can have the message handled by another routine. This is especially useful if the message should go to a particular location on the screen when using curses or to a location on a graphics device (monitor).

Parameters

msg	string (cannot be NULL)

Returns: Terminates with an exit status of EXIT_FAILURE if no external routine is specified by G_set_error_routine()

void G_important_message	(	const char *	msg,
			...
	)

Print a message to stderr even in brief mode (verbosity=1)

Ususally just G_percent()/G_clicker() would be shown at this level. This allows important non-error/warning messages to display as well.

The output format depends on environment variables GRASS_MESSAGE_FORMAT and GRASS_VERBOSE

Parameters

msg	string (cannot be NULL)

int G_info_format ( void )

Get current message format.

Maybe set to either "standard" or "gui" (normally GRASS takes care)

Returns: grass_info_format value
