◆ get_first_output()

Output* get_first_output ( void )

Returns the first output which is active.

◆ get_output_by_name()

Output* get_output_by_name	(	const char *	name,
		const bool	require_active
	)

Returns the output with the given name or NULL.

If require_active is true, only active outputs are considered.

		unsigned int	y
	)

Returns the active (!) output which contains the coordinates x, y or NULL if there is no output which contains these coordinates.

◆ get_output_next()

Output* get_output_next	(	direction_t	direction,
		Output *	current,
		output_close_far_t	close_far
	)

Gets the output which is the next one in the given direction.

If close_far == CLOSEST_OUTPUT, then the output next to the current one will selected. If close_far == FARTHEST_OUTPUT, the output which is the last one in the given direction will be selected.

NULL will be returned when no active outputs are present in the direction specified (note that ‘current’ counts as such an output).

Here is the call graph for this function:

◆ get_output_next_wrap()

Output* get_output_next_wrap	(	direction_t	direction,
		Output *	current
	)

Like get_output_next with close_far == CLOSEST_OUTPUT, but wraps.

For example if get_output_next(D_DOWN, x, FARTHEST_OUTPUT) = NULL, then get_output_next_wrap(D_DOWN, x) will return the topmost output.

This function always returns a output: if no active outputs can be found, current itself is returned.
