** Введение
** --------
** В этом файле описываются команды для управления Winamp
** используя Win32 Message API.
**
** Для начала, вам нужно определить дескриптор главного окна Winamp.
** Однако, если вы пишете плагин, то Winamp сам передаст дескриптор при
** загрузке плагина в соответсвующую структуру (hwndWinamp).
** hwndWinamp:= FindWindow("Winamp v1.x", nil);
**
** После того как вы определили дескриптор, неплохо бы проверить
** номер версии Winamp.
**
** Замечание: в некоторых случаях вы можете использовать PostMessage
** вместо SendMessage.

WM_WA_IPC = WM_USER;
IPC_GetVersion = 0;
(* ver:= SendMessage(hwndWinamp, WM_WA_IPC, 0, IPC_GetVersion);
**
** Для Winamp 2.yx номер версии имеет следующий формат - $20yx, для
** Winamp 1.zx - $1zyx
**

*)
IPC_StartPlay = 102;
(*
** SendMessage(hwndWinamp, WM_WA_IPC, 0, IPC_StartPlay);

*)
IPC_IsPlaying = 104;
(*
** res:= SendMessage(hwndWinamp, WM_WA_IPC, 0, IPC_IsPlaying);
**
** IPC_IsPlaying возвращает статут воспроизведения.

** res:= SendMessage(hwndWinamp, WM_WA_IPC, mode, IPC_GetOutputTime);
**
** IPC_GetOutputTime возвращает текущую позицию в милисекундах в
** текущей песне (mode = 0) или продолжительность песни в
** секундах (mode = 1). Возвращает -1 если ничего не воспроизводится
** или в случае ошибки.
*)
IPC_JumpToTime = 106;
(* требуется Winamp 1.60+
**
** SendMessage(hwndWinamp, WM_WA_IPC, ms, IPC_JumpToTime);

** 0 - в случае успеха.
** 1 - eof
** -1 - ничего не воспроизводится
*)
IPC_WritePlaylist = 120;
(* (requires Winamp 1.666+)
** SendMessage(hwnd_winamp,WM_WA_IPC,0,IPC_WritePlaylist);
**
** IPC_WritePlaylist writes the current playlist to \\Winamp.m3u,

** Kinda obsoleted by some of the 2.x new stuff, but still good for when
** using a front-end (instead of a plug-in)

(* (requires Winamp 2.04+, only usable from plug-ins (not external apps))
** SendMessage(hwnd_winamp,WM_WA_IPC,(WPARAM)"skinname",IPC_SETSKIN);
**
** IPC_SETSKIN sets the current skin to "skinname". Note that skinname
** can be the name of a skin, a skin .zip file, with or without path.
** If path isn't specified, the default search path is the winamp skins
** directory.
*)
IPC_GetSkin = 201;
(* (requires Winamp 2.04+, only usable from plug-ins (not external apps))
** SendMessage(hwnd_winamp,WM_WA_IPC,(WPARAM)skinname_buffer,IPC_GETSKIN);
**
** IPC_GETSKIN puts the directory where skin bitmaps can be found
** into skinname_buffer.

*)
IPC_GetInfo = 126;
(* (requires Winamp 2.05+)
** int inf=SendMessage(hwnd_winamp,WM_WA_IPC,mode,IPC_GETINFO);
