mp3歌曲重新编译

‘壹’ c语言程序设计MP3或MP4文件基本信息的解析

找了个MP3看了下，comment是29个字节。
可参考 http://www.chineselinuxuniversity.net/articles/27374.shtml

拿VC的C语言写了下：
头文件：
#include <stdio.h>

// TODO: reference additional headers your program requires here

#define MP3_ID3_LENGTH 10
typedef struct tag_ID3_INFO
{

} ID3_INFO;

#define IDENTIFY_LEN 3
#define TITLE_LEN 30
#define ARTIST_LEN 30
#define ALBUM_LEN 30
#define YEAR_LEN 4
#define COMMENT_LEN 30
#define GENRE_LEN 1

// IDENTIFY_LEN + TITLE_LEN +...
#define MP3_INFO_LENGTH 128

typedef struct tag_MP3_INFO
{
char Identify[IDENTIFY_LEN + 1]; //TAG三个字母
//这里可以用来鉴别是不是文件信息内容
char Title[TITLE_LEN + 1]; //歌曲名，30个字节
char Artist[ARTIST_LEN + 1]; //歌手名，30个字节
char Album[ARTIST_LEN + 1]; //所属唱片，30个字节
char Year[YEAR_LEN + 1]; //年，4个字节
char Comment[COMMENT_LEN + 1]; //注释，28个字节
char Genre[GENRE_LEN + 1]; //类型 ，1个字节
} MP3_INFO;

C文件：
#include <string.h>

#define MP3_OK 1
#define MP3_ERROR 1

FILE *OpenMp3File(char *pFileName);
int ReadMP3Info(FILE *pFile, MP3_INFO *pstInfo);
int OutputMP3Info(MP3_INFO *pstMp3Info);

int main(int argc, char* argv[])
{
FILE *pFile = NULL;
MP3_INFO stMp3Info = {0};
char *pfname = "E:\\Project\\MP3\\test.MP3";

pFile = OpenMp3File(pfname);
if (NULL == pFile)
{
return MP3_ERROR;
}

ReadMP3Info(pFile, &stMp3Info);

printf("\r\nMP3 file: %s", pfname);
OutputMP3Info(&stMp3Info);

printf("Hello World!\n");
return MP3_OK;
}

FILE *OpenMp3File(char *pFileName)
{
FILE *pFile = NULL;
pFile = fopen(pFileName,"rb");
if (NULL==pFile)
{
printf("open read file error!!");
return NULL;
}

return pFile;
}

int ReadMP3Info(FILE *pFile, MP3_INFO *pstInfo)
{
int len = 0;
if ((NULL == pFile) || (NULL == pstInfo))
{
return MP3_ERROR;
}

fseek(pFile, 0, SEEK_END);
len = ftell(pFile);
if (len <= (MP3_INFO_LENGTH + MP3_ID3_LENGTH))
{
return MP3_ERROR;
}

memset(pstInfo, 0, sizeof(MP3_INFO));

fseek(pFile, -MP3_INFO_LENGTH, SEEK_END);
len = fread((char *)(pstInfo->Identify), 1, IDENTIFY_LEN, pFile);
len += fread((char *)(pstInfo->Title), 1, TITLE_LEN, pFile);
len += fread((char *)(pstInfo->Artist), 1, ARTIST_LEN, pFile);
len += fread((char *)(pstInfo->Album), 1, ALBUM_LEN, pFile);
len += fread((char *)(pstInfo->Year), 1, YEAR_LEN, pFile);
len += fread((char *)(pstInfo->Comment), 1, COMMENT_LEN, pFile);
len += fread((char *)(pstInfo->Genre), 1, GENRE_LEN, pFile);
if (MP3_INFO_LENGTH != len)
{
return MP3_ERROR;
}

return MP3_OK;
}

int OutputMP3Info(MP3_INFO *pstMp3Info)
{
printf("\r\nTag : %s", pstMp3Info->Identify);
printf("\r\nTitle : %s", pstMp3Info->Title);
printf("\r\nArtist : %s", pstMp3Info->Artist);
printf("\r\nAlbum : %s", pstMp3Info->Album);
printf("\r\nYear : %s", pstMp3Info->Year);
printf("\r\nComment: %s", pstMp3Info->Comment);

return MP3_OK;
}

测试：
MP3 file: E:\Project\MP3\test.MP3
Tag : TAG
Title : TrackTitle
Artist : ArtistName
Album : AlbumTitle
Year : 2012

‘贰’ 请问易语言怎么将MP3文件放到自己要编译的程序中。
