请教下，
我现在想把fatfs v0.12版本改成 使用 fatfs v0.11，出现下面的情况，该如何修改啊 ？？
fatfs v0.12 的版本里面有个
if(totsize == 0) //仅仅是单个文件复制
{
totsize = fsrc->obj.objsize; // 这个是 fatfs v0.12 版本里面的，但是在 fatfs v0.11里面没有，那么此处应该对应 v0.11版本里面的哪个变量啊 ？？？
lcpdsize = 0;
curpct = 0;
}
在fatfs v0.11 里面找到 DWORD clust; /* Current cluster of fpter (not valid when fprt is 0) */
对应 fatfs v0.11 fsrc->fsize; // 如果改成这样，不知道对不对 ??????????????????????????????
/* 下面这个是 fatfs v0.11 版本 */
/* File object structure (FIL) */
typedef struct {
#if !_FS_TINY
union{
UINT d32[_MAX_SS/4]; /* Force 32bits alignement */
BYTE d8[_MAX_SS]; /* File data read/write buffer */
}buf;
#endif
FATFS* fs; /* Pointer to the related file system object (**do not change order**) */
WORD id; /* Owner file system mount ID (**do not change order**) */
BYTE flag; /* Status flags */
BYTE err; /* Abort flag (error code) */
DWORD fptr; /* File read/write pointer (Zeroed on file open) */
DWORD fsize; /* File size */
DWORD sclust; /* File start cluster (0:no cluster chain, always 0 when fsize is 0) */
DWORD clust; /* Current cluster of fpter (not valid when fprt is 0) */
DWORD dsect; /* Sector number appearing in buf[] (0:invalid) */
#if !_FS_READONLY
DWORD dir_sect; /* Sector number containing the directory entry */
BYTE* dir_ptr; /* Pointer to the directory entry in the win[] */
#endif
#if _USE_FASTSEEK
DWORD* cltbl; /* Pointer to the cluster link map table (Nulled on file open) */
#endif
#if _FS_LOCK
UINT lockid; /* File lock ID origin from 1 (index of file semaphore table Files[]) */
#endif
} FIL;
