DIR

The DIR structure is used for the work area to read a directory by f_oepndir()/f_readdir() function. Application program must not modify any member in this structure.

typedef struct {
    FATFS*  fs;         /* Pointer to the owner file system object */

    DWORD   clust;      /* Current cluster */
    DWORD   sect;       /* Current sector */
    BYTE*   dir;        /* Pointer to the current SFN entry in the win[] */
