	Prints the partition table partitions with count partitions to standard output.

void	rtems_bdpart_to_partition_type (uint8_t mbr_type, uuid_t type)
	Returns the partition type for the MBR partition type value mbr_type in type.

bool	rtems_bdpart_to_mbr_partition_type (const uuid_t type, uint8_t *mbr_type)
	Converts the partition type in type to the MBR partition type. More...
