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).

Referenced by _tree_next(), get_output_next_wrap(), and move_to_output_directed().

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.
