checkValidPartition()

void openmsx::DiskImageUtils::checkValidPartition	(	SectorAccessibleDisk &	disk,
		unsigned	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..31].

format()

void openmsx::DiskImageUtils::format	(	SectorAccessibleDisk &	disk,
		bool	dos1 = false
	)

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
dos1	set to true if you want to force dos1 formatting (boot sector)
