format() [1/2]

void openmsx::DiskImageUtils::format	(	SectorAccessibleDisk &	disk,
		MSXBootSectorType	bootType

Format the given disk (= a single partition).

The formatting depends on the size of the image.

Parameters

disk	The disk/partition image to be formatted.
bootType	The boot sector type to use.

getPartition()

Partition & openmsx::DiskImageUtils::getPartition	(	const SectorAccessibleDisk &	disk,
		unsigned	partition,
		SectorBuffer &	buf
	)

Gets the requested partition.

Checks whether: the disk is partitioned the specified partition exists throws a CommandException if one of these conditions is false

Parameters

disk	The disk to check.
partition	Partition number, in range [1..].
buf	Sector buffer for partition table.

Returns

Reference to partition information struct in sector buffer.
