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
