From fcf36dd4f9879a82342e5606535d2dcf46d1de2a Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Mon, 17 May 2010 12:34:05 +0000 Subject: Simplify mpegplayer a bit and use array-based lists rather than linked lists for stream management. Move a couple useful functions to handle pointer arrays from kernel.c into general.c; mpeglayer now makes use of them. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26101 a1c6a512-1295-4272-9138-f99709370657 --- apps/plugins/mpegplayer/mpeg_linkedlist.h | 71 ------------------------------- 1 file changed, 71 deletions(-) delete mode 100644 apps/plugins/mpegplayer/mpeg_linkedlist.h (limited to 'apps/plugins/mpegplayer/mpeg_linkedlist.h') diff --git a/apps/plugins/mpegplayer/mpeg_linkedlist.h b/apps/plugins/mpegplayer/mpeg_linkedlist.h deleted file mode 100644 index d4f8305d7d..0000000000 --- a/apps/plugins/mpegplayer/mpeg_linkedlist.h +++ /dev/null @@ -1,71 +0,0 @@ -/*************************************************************************** - * __________ __ ___. - * Open \______ \ ____ ____ | | _\_ |__ _______ ___ - * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / - * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < - * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ - * \/ \/ \/ \/ \/ - * $Id$ - * - * Linked list API declarations - * - * Copyright (c) 2007 Michael Sevakis - * - * This program is free software; you can redistribute it and/or - * modify it under the terms of the GNU General Public License - * as published by the Free Software Foundation; either version 2 - * of the License, or (at your option) any later version. - * - * This software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY - * KIND, either express or implied. - * - ****************************************************************************/ -#ifndef MPEG_LINKEDLIST_H -#define MPEG_LINKEDLIST_H - -struct list_item -{ - struct list_item *prev; /* previous item in list */ - struct list_item *next; /* next item in list */ -}; - -/* Utility macros to help get the actual structure pointer back */ -#define OFFSETOF(type, membername) ((off_t)&((type *)0)->membername) -#define TYPE_FROM_MEMBER(type, memberptr, membername) \ - ((type *)((intptr_t)(memberptr) - OFFSETOF(type, membername))) - -/* Initialize a master list head */ -void list_initialize(struct list_item *master_list_head); - -/* Are there items after the head item? */ -bool list_is_empty(struct list_item *head_item); - -/* Does the item belong to a list? */ -bool list_is_item_listed(struct list_item *item); - -/* Is the item a member in a particular list? */ -bool list_is_member(struct list_item *master_list_head, - struct list_item *item); - -/* Remove an item from a list - no head item needed */ -void list_remove_item(struct list_item *item); - -/* Add a list item after the base item */ -void list_add_item(struct list_item *head_item, - struct list_item *item); - -/* Clear list items after the head item */ -void list_clear_all(struct list_item *head_item); - -/* Enumerate all items after the head item - passing each item in turn - * to the callback as well as the data value.
