Detailed Description

Those functions deal with style for random maps.

Todo:: couldn't load_dir() be merged with a function in common library?

Definition in file style.c.

Function Documentation

mapstruct* find_style	(	const char *	dirname,
		const char *	stylename,
		int	difficulty
	)

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.

Todo:: better document.

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.
