请教一个数据类型不兼容的问题，源程序相关的如下：
struct FAT32_FAT_Item
{
unsigned char Item[4];
};
struct FAT32_FAT
{
struct FAT32_FAT_Item Items[128];
};
unsigned long lb2bb(unsigned char *dat,unsigned char len)
{
unsigned long temp=0;
unsigned long fact=1;
unsigned char i=0;
for(i=0;i<len;i++)
{
temp+=dat*fact;
fact*=256;
}
return temp;
}
unsigned long temp;
struct FAT32_FAT *pFAT;
struct FAT32_FAT_Item *pFAT_Item;
temp=((LastCluster/128)+Init_Arg.FirstFATSector); FAT32_ReadSector(temp,FAT32data_buff);
pFAT=(struct FAT32_FAT *)FAT32data_buff;
pFAT_Item=&((pFAT->Items)[LastCluster%128]);
//在算出的扇区中提取簇项
lb2bb(pFAT_Item,4); //返回下一簇号 ***************************这里出现问题
编译后出现的错误为：error:
"fat32.c", line 225: error: argument of type "struct FAT32_FAT_Item *" is incompatible with parameter of type "unsigned char * "
不知道该如何解决这个冲突，敬请大虾指教，谢谢。
