Function Documentation

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.

{
  return FATFS_LinkDriverEx(drv, path, 0);
}
