Block * Image_allocateAt	(	const Image *	self,
		const BlockPosition *	pos
	)

This tries to allocate a given block. A module reserving this block is asked to release it if necessary. It will fail if the block is already allocated or a module reserving it refuses to release it.

Parameters

self	the image
pos	the position of the block to allocate

Returns: the allocated block object or 0 if allocation was not possible

IBlockAllocator * Image_allocator ( const Image * self )

Get a pointer to the IBlockAllocator instance currently in use.

Parameters

self the image

Returns: the allocator

Block * Image_block	(	const Image *	self,
		const BlockPosition *	pos
	)

This also locates blocks on tracks from modules providing extra tracks

Parameters

self	the image
pos	the position of the block to get

Returns: the block object or 0 if no block wit the given position exists

BlockStatus Image_blockStatus	(	const Image *	self,
		const BlockPosition *	pos
	)

Parameters

self	the image
pos	the position of the block

Returns: the status of the block

void Image_setAllocator	(	Image *	self,
		IBlockAllocator *	allocator
	)

Set an IBlockAllocator instance to handle block allocations while writing files. The Image class has a default allocator that is used if this is never called – the default allocator is looking sequentially for free blocks, starting at track #1.

Parameters

self	the image
allocator	the allocator to use

Track * Image_track	(	const Image *	self,
		int	tracknum
	)

This also tries to get a track from modules providing extra tracks

Parameters

self	the image
tracknum	the number of the track to get

Returns: the track object or 0 if no track with that number exists
