The f_stat function checks the existence of a file or sub-directory.
FRESULT f_stat ( const TCHAR* path, /* [IN] Object name */ FILINFO* fno /* [OUT] FILINFO structure */ );
FR_OK, FR_DISK_ERR, FR_INT_ERR, FR_NOT_READY, FR_NO_FILE, FR_NO_PATH, FR_INVALID_NAME, FR_INVALID_DRIVE, FR_NOT_ENABLED, FR_NO_FILESYSTEM, FR_TIMEOUT, FR_NOT_ENOUGH_CORE
The f_stat function checks the existence of a file or sub-directory. If not exist, the function returns with FR_NO_FILE. If exist, the function returns with FR_OK and the informations about the object, size, timestamp and attribute, is stored to the file information structure. For details of the file information, refer to the FILINFO structure and f_readdir function.
Available when FF_FS_MINIMIZE == 0.
