DIR

The DIR structure is used for the work area to read a directory by f_oepndir, f_readdir, f_findfirst and f_findnext function. Application program must not modify any member in this structure, or any file on the volume can be collapsed.

typedef struct {
    FFOBJID obj;        /* Object identifier */
    DWORD   dptr;       /* Current read/write offset */
    DWORD   clust;      /* Current cluster */
    DWORD   sect;       /* Current sector */
    BYTE*   dir;        /* Pointer to the current SFN entry in the win[] */
    BYTE*   fn;         /* Pointer to the SFN buffer (in/out) {file[8],ext[3],status[1]} */
#if FF_USE_LFN
    DWORD   blk_ofs;    /* Offset of the entry block (0xFFFFFFFF:Invalid) */
    WCHAR*  lfn;        /* Pointer to the LFN working buffer (in/out) */
#endif
#if FF_USE_FIND
    const TCHAR*  pat;  /* Ponter to the matching pattern */
#endif
