链接时要指定库文件。VC++是vfw32.lib, GCC是libvfw32.a.
我在谈含橡VC6.0和GCC/MinGW 3.3.1下都通过了。
假设程序名是MyPlay, 目录下还有一个aaa.mp3, 运行MyPlay aaa.mp3即可。
注意Sleep(50000)是让他最多播放50秒。没有Sleep()的话，窗口一闪老物就退出了。
具体的MCI函数请查有关资料。
#include <windows.h>
#include <vfw.h>
int main(int argc, char* argv[])
{
if (argc>1) {
HWND MyPlayer = MCIWndCreate(NULL,GetModuleHandle(NULL), 0, argv[1])
MCIWndPlay(MyPlayer)
Sleep(50000)
}
return 0
}
这个程序还可以播放MIDI, AVI, WMV, MPG等影音文件。
如果只是后台播放MIDI或MP3，不想显示那个没有用的窗口，把MCIWndCreate()第三个参数0改成WS_POPUP即可。
如果想精确控制Sleep()至MP3播放结束，可以改成 Sleep(MCIWndGetLength(MyPlayer))
对含旁于mp3, MCIWndGetLength()返回值的单位是毫秒，可以直接用于Sleep()延时。
对于mpg, MCIWndGetLength()返回值的单位是帧数，还要转换成毫秒才能用于Sleep().
具体MCIWndGetLength()返回值的单位是什么，可以调用MCIWndGetTimeFormat()来查询。

曲谱存贮格式 unsigned char code MusicName{音高，音长，音高，音长...., 0,0}末尾:0,0 表示结束(Important)
音高由三位数字组成：
个位是表示 1~7 这七个音符
十位是表示音符所在的音区:1-低音，2-中音，3-高音
百位表示这个音符是否要升半音: 0-不升，1-升半音。
音长最多由三位数字组成：
个位表示音符的时值，其对应关系是：
|数值(n): |0 |1 |2 |3 | 4 | 5 | 6
|几分音符: |1 |2 |4 |8 |16 |32 |64 音符=2^n
十位表示音符的演奏效果(0-2): 0-普通，1-连音，2-顿音
百位是符点位: 0-无符点，1-有符点
调用演奏子程序的格式
Play(乐曲名,调号,升降八度,演奏速度)
|乐曲名 : 要播放的乐曲指针,结尾以(0,0)结束
|调号(0-11) : 是指乐曲升多少个半音演奏
|升降八度(1-3) : 1:降八度, 2:不升不降, 3:升八度
|演奏速度(1-12000): 值越大速度越快
