mapstruct* find_style	(	const char *	dirname,

Loads and returns the map requested.

Dirname, for example, is "/styles/wallstyles", stylename, is, for example, "castle", difficulty is -1 when difficulty is irrelevant to the style. If dirname is given, but stylename isn't, and difficult is -1, it returns a random style map. Otherwise, it tries to match the difficulty given with a style file, named style_name_# where # is an integer

Parameters:

dirname	where to look.
stylename	style to use, can be NULL.
difficulty	style difficulty.

Returns:

style, or NULL if none suitable.

map
x
y	where to put a key.
keycode	keycode is the key's code.
door_flag	if NO_PASS_DOORS won't cross doors or walls to keyplace, PASS_DOORS will. if PASS_DOORS is set, the x & y values that are passed in are basically meaningless - IMO, it is a bit of misnomer, as when it is set, it just randomly chooses spaces on the map, ideally finding a close monster, to put the key in. In fact, if PASS_DOORS is set, there is no guarantee that the keys will be on both sides of the door - it may happen by randomness, but the code doesn't work to make sure it happens.
n_keys	number of keys to place. If 1, it will place 1 key. Else, it will place 2-4 keys.
RP	random map parameters.

Returns:

1 if key was successfully placed, 0 else.

int load_dir	(	const char *	dir,
		char ***	namelist,
		int	skip_dirs
	)

This is our own version of scandir/select_regular_files/sort.

To support having subdirectories in styles, we need to know if in fact the directory we read is a subdirectory. However, we can't get that through the normal dirent entry. So instead, we do our own where we do have the full directory path so can do stat calls to see if in fact it is a directory. dir is the name of the director to scan. namelist is the array of file names returned. IT needs to be freed by the caller. skip_dirs controls our behavioru - if nonzero, we don't skip any subdirectories - if zero, we store those away, since there are cases where we want to choose a random directory.

Parameters:

	dir	directory to list.
[out]	namelist	list of files found.
	skip_dirs	if non 0, don't list directories.

Returns:

-1 if dir is invalid, number of files else.

int surround_flag3	(	mapstruct *	map,
		int	i,
		int	j,
		RMParms *	RP
	)

Check a map for blocked spots.

Since this is part of the random map code, presumption is that this is not a tiled map. What is considered blocking and not is somewhat hard coded.

Parameters:

map
i
j	spot to look.
RP	map parameters.

Returns:

combination of:

• 1 = blocked on left.
• 2 = blocked on right.
• 4 = blocked on above.
• 8 = blocked on below.

Check a map for spots with walls.

Since this is part of the random map code, presumption is that this is not a tiled map. What is considered blocking and not is somewhat hard coded.

Parameters:

map

j	spot to look.
RP	map parameters.

Returns:

char** symmetrize_layout	(	char **	maze,
		int	sym,
		RMParms *	RP
	)

Takes a map and makes it symmetric: adjusts Xsize and Ysize to produce a symmetric map.

Parameters:

maze	layout to symmetrize. Will be free()d by this function.
sym	how to make symetric, a Random map symetry value.
RP	map parameters.

Returns:

new layout, must be free()d by caller.

void unblock_exits	(	mapstruct *	map,

This function unblocks the exits.

We blocked them to keep things from being dumped on them during the other phases of random map generation.

Parameters:

map	map to alter.
maze	map layout.
RP	map generation parameters.

Returns true if square x,y has P_NO_PASS set, which is true for walls and doors but not monsters.

This function is not map tile aware.

Parameters:

m
x
y	map and coordinates to check for.

Returns:

non zero if blocked, 0 else.
