FatFS中的FILINFO介绍

当调用FatFS中的f_readdir函数返回FILINFO值的时候，大家如果直接看FILINFO里面的值可能看不懂。因为里面的值需要大家转换一下，FILINFO的具体格式如下：

The FILINFO structure holds a file information returned by f_stat and f_readdir function.

typedef struct {
    DWORD fsize;      /* File size */
    WORD fdate;      /* Last modified date */
    WORD ftime;      /* Last modified time */
    BYTE fattrib;    /* Attribute */
    TCHAR fname[13]; /* Short file name (8.3 format) */
#if _USE_LFN
    TCHAR* lfname;    /* Pointer to the LFN buffer */
    int   lfsize;     /* Size of the LFN buffer in unit of TCHAR */
#endif
} FILINFO;
Members
fsize
Indicates size of the file in unit of byte. Always zero for directories.
fdate
Indicates the date that the file was modified or the directory was created.
bit15:9
Year origin from 1980 (0..127)
bit8:5
Month (1..12)
bit4:0
Day (1..31)
ftime
Indicates the time that the file was modified or the directory was created.
bit15:11
Hour (0..23)
bit10:5
Minute (0..59)
bit4:0
Second / 2 (0..29)
fattrib
Indicates the file/directory attribute in combination of AM_DIR, AM_RDO, AM_HID, AM_SYS and AM_ARC.
fname[]   www.zzzyk.com
Indicates the file/directory name in 8.3 format null-terminated string. It is always returnd with upper case on non-LFN configuration but it can be returned with lower case on LFN configuration.
lfname
Pointer to the LFN buffer to store the read LFN. This member must be initialized by application prior to use this structure. Not available on non-LFN configuration.
lfsize
Size of the LFN buffer in unit of TCHAR. This member must be initialized by application prior to use this structure. Not available on non-LFN configuration.
