#define IPC_GETPLAYLISTFILE 211
/* (requires Winamp 2.04+, only usable from plug-ins (not external apps))
** char *name=SendMessage(hwnd_winamp,WM_WA_IPC,index,IPC_GETPLAYLISTFILE);
**
** IPC_GETPLAYLISTFILE gets the filename of the playlist entry [index].
** returns a pointer to it. returns NULL on error.
*/
下面这句在delphi里怎么写啊
char *name=SendMessage(hwnd_winamp,WM_WA_IPC,index,IPC_GETPLAYLISTFILE);

卷起千堆雪tyn等:
他返回一个指针,应该是指针指向的地址吧
指向字符串的指针
我的目的要取这个字符串

以上各位,我试过代码
但都不能取得winamp播放的文件名
const
WM_WA_IPC = WM_USER;
IPC_GETPLAYLISTFILE = 211;
函数说明说能得到文件名
IPC_GETPLAYLISTFILE gets the filename of the playlist entry [index].
请大家帮帮忙

IPC_GETPLAYLISTFILE = 211只能在插件里用
beta是对的
谢谢!
