Data Structures
struct	vfswriter
	Playlist writing module object. Matching is performed by extension. More...
Defines
#define	NUM_MODULES   (sizeof modules / sizeof(struct vfsmodule))
	The number of virtual file system modules currently available in the application.
#define	NUM_WRITERS   (sizeof writers / sizeof(struct vfswriter))
	The number of VFS writing modules currently available in the application.
Functions
static char *	vfs_path_concat (const char *dir, const char *file, int strict)
	Concatenate a path- and filename. The resulting filename will not contain /./'s and /../'s.
const char *	vfs_lockup (void)
	Try to lock the application in a specified directory on startup. This function returns an error message.
static void	vfs_dealloc (struct vfsent *ve)
	Deallocates the data structures for a VFS entity.
struct vfsref *	vfs_lookup (const char *filename, const char *name, const char *basepath, int strict)
	Create a VFS reference from a filename. The name argument is optional. It only allows you to display entities with a different name (inside playlists). When setting the basepath variable, all relative pathnames are appended to the basepath. When unset, it can only open absolute filenames. When forcing strict pathnames, application-implemented features like ~ are discarded.
struct vfsref *	vfs_dup (const struct vfsref *vr)
	Duplicate the reference by increasing the reference count.
void	vfs_close (struct vfsref *vr)
	Decrease the reference count of the entity and deallocate the entity when no references are left. The reference itself is also deallocated.
int	vfs_populate (const struct vfsref *vr)
	Populate the VFS entity with references to its children.
void	vfs_unfold (struct vfslist *vl, const struct vfsref *vr)
	Recursively expand a VFS reference to all their usable children and append them to the specified list.
void	vfs_locate (struct vfslist *vl, const struct vfsref *vr, const struct vfsmatch *vm)
	Recursively search through a VFS reference and add all matching objects to a list. The VFS reference itself will be excluded from the results.
struct vfsref *	vfs_write_playlist (const struct vfslist *vl, const struct vfsref *vr, const char *filename)
	Write a VFS list to a PLS file on disk.
int	vfs_delete (const char *filename)
	Delete a local file. Use with caution. ;-).
FILE *	vfs_fopen (const char *filename, const char *mode)
	fopen()-like routine that uses VFS path expansion.
int	vfs_fgets (char *str, size_t size, FILE *fp)
	fgets()-like routine that performs newline-stripping.
struct vfsmatch *	vfs_match_new (const char *str)
	Compile a regular expression for matching.
void	vfs_match_free (struct vfsmatch *vm)
	Deallocate a compiled regular expression.
Variables
static struct vfsmodule	modules []
	List of available virtual filesystem modules and their options and functions.
static struct vfswriter	writers []
	List of VFS writing modules. The first item in the list is used when no matching extension was found. In that case, the extension of the first item will be appended to the filename.
