作业贴，100分，用！该怎么处理

作业贴，100分，急用！
作业描述：
读取一个ini文件到buffer中，根据ini文件中的主字段与次字段，查询ini文件输出对应的数值(去除 '可能 '遇到的注释等内容)。
ini文件内容如下：
[First1]
        [Second1]=aaaa       //注释
        [Second2]=bbbb
[First2]
        [Second1]=cccc       //注释
        [Second2]=dddd
[First3]
        [Second1]=eeee       //注释
        [Second2]=ffff       /*注释*/



[解决办法]
输出是什么？

#include <stdlib.h>

#include <stdio.h>
void cut(char *tmp)
{
char *ptr;
ptr=tmp;
if(tmp==NULL)return;
while(*ptr)
if(*ptr== '\n '||*ptr== '\r ')
{
*ptr=0;
break;
}
else ptr++;

int pos=0;
pos=strcspn(tmp, "// ");
ptr=tmp;
*(ptr+pos)= '\0 ';
pos=strcspn(tmp, "/* ");
*(ptr+pos)= '\0 ';
}
char * readini(char *filename,char *_group,char *_member,char *value)
{
FILE *file;
char buf1[1024],buf2[1024],buf3[1024];
int len,flag=0;
char *ptr,*str;
char *group,*member;
if(!_group||!_member)return NULL;

group=(char*)malloc(strlen(_group)+2);
member=(char *)malloc(strlen(_member)+2);

memset(group,0,strlen(_group)+2);
memset(member,0,strlen(_member)+2);

sprintf(group, "[%s] ",_group);
sprintf(member, "[%s] ",_member);

if((file=fopen(filename, "r "))==NULL)
{
free(group);
free(member);
return NULL;
}
memset(buf1,0,sizeof(buf1));

while(fgets(buf1,sizeof(buf1),file))
{
cut(buf1);
if(strlen(buf1)==0)continue;
if(strcmp(buf1,group)==0)
{
flag=1;
continue;
}
if(flag&&(strcspn(buf1,member)==0))
{
ptr=buf1;
ptr+=strlen(member);
ptr++;
strcpy(value,ptr);
break;
}
}
fclose(file);
free(group);
free(member);
return value;
}

int main()
{

char buf1[1024];
memset(buf1,0,sizeof(buf1));
readini( "test.txt ", "First2 ", "Second2 ",buf1);
printf( "%s\n ",buf1);
}

这个可用,不过没考虑换行的多行注释这中情况.

简单写了一下

return -1;

memset(szFirst,0,sizeof(szFirst));
memset(szSecond,0,sizeof(szSecond));
memset(szValue,0,sizeof(szValue));

while (!feof(fp))
{
if (fgets(szBuff, sizeof(szBuff), fp) == NULL)
break ;

if( trim(szBuff) <0 )
continue ;

if( pCur != NULL ) //[Second1]
{

else

}
}
else // [First1]

}
}

fclose(fp);

return(0);
}

int trim(char *szBuff)

}

//去掉 /**/ 注释

}

//去掉后面的 // 注释

return(0);
