Macros
#define	FATFS_YEAR_OFFSET (1980)
	The year in FatFs timestamps is relative to this offset.

#define	EPOCH_YEAR_OFFSET (1970)
	The epoch offset is used to convert between FatFs and time_t timestamps.

#define	FATFS_MAX_VOL_STR_LEN (6)
	size needed for volume strings like "n:/" where n is the volume id

#define	FATFS_MOUNT_OPT (1)
	0:mount on first file access, 1 mount in f_mount() call

#define	FATFS_MAX_ABS_PATH_SIZE (FATFS_MAX_VOL_STR_LEN + VFS_NAME_MAX + 1)
	Size of path buffer for absolute paths. More...

Typedefs

	FatFs instance descriptor.

typedef struct fatfs_file_desc	fatfs_file_desc_t
	FatFs file instance descriptor.

Variables
const vfs_file_system_t	fatfs_file_system
	The FatFs vfs driver, a pointer to a fatfs_desc_t must be provided as vfs_mountp::private_data.

Macro Definition Documentation

#define FATFS_MAX_ABS_PATH_SIZE (FATFS_MAX_VOL_STR_LEN + VFS_NAME_MAX + 1)

Size of path buffer for absolute paths.

Most FatFs file operations need an absolute path. This defines the size of the needed buffer to circumvent stack allocation within vfs-wrappers
