Function Documentation

FATFS_GetAttachedDriversNbr()

uint8_t FATFS_GetAttachedDriversNbr

(

void

)

Gets number of linked drivers to the FatFs module.

Parameters

None

Return values

Number

of attached drivers.

Definition at line 116 of file ff_gen_drv.c.

FATFS_LinkDriver()

uint8_t FATFS_LinkDriver	(	const Diskio_drvTypeDef *	drv,
		char *	path
	)

Links a compatible diskio driver and increments the number of active linked drivers.

Note

The number of linked drivers (volumes) is up to 10 due to FatFs limits

Parameters

drv	pointer to the disk IO Driver structure
path	pointer to the logical drive path

Return values

Returns

0 in case of success, otherwise 1.

Definition at line 68 of file ff_gen_drv.c.

FATFS_LinkDriverEx()

uint8_t FATFS_LinkDriverEx	(	const Diskio_drvTypeDef *	drv,
		char *	path,
		uint8_t	lun
	)

Links a compatible diskio driver/lun id and increments the number of active linked drivers.

Note

The number of linked drivers (volumes) is up to 10 due to FatFs limits.

Parameters

drv	pointer to the disk IO Driver structure
path	pointer to the logical drive path
lun	: only used for USB Key Disk to add multi-lun management else the parameter must be equal to 0

Return values

Returns

0 in case of success, otherwise 1.

Definition at line 39 of file ff_gen_drv.c.

FATFS_UnLinkDriver()

uint8_t FATFS_UnLinkDriver

(

char *

path

)

Unlinks a diskio driver and decrements the number of active linked drivers.

Parameters

path	pointer to the logical drive path

Return values

Returns

0 in case of success, otherwise 1.

Definition at line 106 of file ff_gen_drv.c.

FATFS_UnLinkDriverEx()

uint8_t FATFS_UnLinkDriverEx	(	char *	path,
		uint8_t	lun
	)

Unlinks a diskio driver and decrements the number of active linked drivers.

Parameters

path	pointer to the logical drive path
lun	: not used

Return values

Returns

0 in case of success, otherwise 1.
