From d3b763a48c09a60a0c0b5ccb6cccd9376875c470 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Wed, 30 Dec 2009 23:27:37 +0100 Subject: input_stream: return allocated input_stream objects Major API redesign: don't let the caller allocate the input_stream object. Let each input plugin allocate its own (derived/extended) input_stream pointer. The "data" attribute can now be removed, and all input plugins simply cast the input_stream pointer to their own structure (with an "struct input_stream base" as the first attribute). --- src/archive/bz2_archive_plugin.c | 35 +++++++------ src/archive/iso9660_archive_plugin.c | 27 +++++----- src/archive/zzip_archive_plugin.c | 29 +++++------ src/archive_plugin.c | 6 +-- src/archive_plugin.h | 9 ++-- src/decoder/wavpack_plugin.c | 27 +++++----- src/decoder_thread.c | 42 +++++++-------- src/input/archive_input_plugin.c | 19 ++++--- src/input/curl_input_plugin.c | 97 +++++++++++++++++------------------ src/input/file_input_plugin.c | 44 +++++++++------- src/input/mms_input_plugin.c | 27 +++++----- src/input/rewind_input_plugin.c | 77 +++++++++++++-------------- src/input/rewind_input_plugin.h | 6 +-- src/input_plugin.h | 3 +- src/input_stream.c | 24 ++++----- src/input_stream.h | 27 +++++----- src/playlist/lastfm_playlist_plugin.c | 44 ++++++++-------- src/playlist_list.c | 6 ++- src/playlist_list.h | 4 +- src/playlist_queue.c | 21 ++++---- src/song_update.c | 17 +++--- 21 files changed, 292 insertions(+), 299 deletions(-) (limited to 'src') diff --git a/src/archive/bz2_archive_plugin.c b/src/archive/bz2_archive_plugin.c index 07d174403..75b4b1ece 100644 --- a/src/archive/bz2_archive_plugin.c +++ b/src/archive/bz2_archive_plugin.c @@ -45,10 +45,12 @@ struct bz2_archive_file { char *name;
