辛苦大家帮我看一个关于内存播放wav的问题

[ga6840]

代码如下：

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<malloc.h>
#include <windows.h>

struct wav_head
{
    unsigned long wav_id;
    unsigned int wav_size;
    unsigned int type;
    unsigned int fmt_id;
    unsigned int fmt_size;
    unsigned short format_tag;
    unsigned short channels;
    unsigned int sample_per_sec;
    unsigned int avg_bytes_per_sec;
    unsigned short block_align;
    unsigned short bits_per_sample;
    //unsigned short attach_info;
    unsigned int data_id;
    unsigned int date_size;
};

int main()
{   
    char *pbuf;
    int i,len;
    FILE *fp;
    
    struct wav_head *test;
    test=(struct wav_head *)malloc(sizeof(struct wav_head));
	len=55552; 
    pbuf=(char *)malloc(55552);
    fp=fopen("test2.wav","w");

    test->wav_id=0x46464952;  //RIFF
    test->wav_size=len+44-8;    
    test->type=0x45564157;      //WAVE
    
    test->fmt_id=0x20746d66;  //fmt
    test->fmt_size=0x10;
    test->format_tag=0x1;
    test->channels=0x1;
    test->sample_per_sec=0x3e80;
    test->avg_bytes_per_sec=0x7d00;
    test->block_align=0x2;
    test->bits_per_sample=0x10;
         
    test->data_id=0x61746164;  //data
    test->date_size=len; 
    
    
    
    
    for(i=0;i<len;i++)
    {
        //pbuf[i]=rand()%256;
        pbuf[i]=i%256;
    }
    fwrite(test,sizeof(struct wav_head),1,fp);
    fwrite(pbuf,sizeof(char),len,fp);
	
    char* wavwav=new char[sizeof(struct wav_head)+55552];
    memcpy(wavwav  ,   (char*)test     ,sizeof(wav_head));
    memcpy(wavwav +  sizeof(wav_head)  ,(char*)pbuf,55552);

	sndPlaySound(NULL,SND_MEMORY|SND_ASYNC);//stop the sound if there is a sound
	sndPlaySound((const char *)&test,SND_MEMORY|SND_ASYNC);//return immediately
	

    free(pbuf);
    free(test);
    fclose(fp);
	
	while(1);
    return 0;
}

包含有：kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib comctl32.lib dxerr8.lib winmm.lib dsound.lib dxguid.lib

程序执行后 生成的wav可以播放 但

问题是：
我尝试想用sndPlaySound播放内存里的wav却没达到效果 ，没有任何声音播放 ，为什么？

谢谢各位！

播放内存里的 需要

waveOutOpen 打开播放设备

waveOutPrepareHeader 为播放设备准备数据缓冲

waveOutWrite 播放

void CALLBACK RingWaveOutProc( HWAVEOUT hwo, UINT uMsg, DWORD dwInstance, DWORD dwParam1, DWORD dwParam2)

播放声音的回调函数

从你的程序来看似乎是
sndPlaySound((const char *)wavwav,SND_MEMORY|SND_ASYNC);
应该是wavwav
或者至少应该写
sndPlaySound((const char *)test,SND_MEMORY|SND_ASYNC);
无需取地址

哎！！！！！！太傻啦
我试了试 没声就没。。。
可惜100分
不过谢谢goodname

我发现自己写的就是tm难查出错
