Function Documentation

void connect_spirals	(	int	xsize,
		int	ysize,
		int	sym,
		char **	layout
	)

Connects disjoint spirals which may result from the symmetrization process.

Parameters:

xsize
ysize	layout size.
sym	one of the SYM_xxx values.
layout	layout to alter.

Parameters:

xsize
ysize	layout size.
option	combination of SPIRAL_xxx values.

Returns:

Here is the caller graph for this function:

int surround_check	(	char **	layout,
		int	i,
		int	j,
		int	Xsize,
		int	Ysize
	)

Checks free spots around a spot.

Parameters:

layout	map layout.
i
j	coordinates to check.
Xsize
Ysize	size of the layout.

Returns:

combination of the following values:

• 1 = free space to left,
• 2 = free space to right,
• 4 = free space above
• 8 = free space below

Todo:

there is an equivalent function in another layout, merge them together.
