Detailed Description

Virtual memory interface to swap memory chunks onto disk.

Note

The class only supports the NeFS as of right now, as it is using forks to write data into disk.

Read()

SWAP_DISK_HEADER * Kernel::DiskSwapInterface::Read	(	const Char *	fork_name,
		SizeT	fork_name_len,
		SizeT	data_len )

Read memory chunk from disk.

Parameters

name	The swap name to recognize this memory region.
name_len	length of fork name.
data	the data packet length.

Returns

Whether the swap was fetched to disk, or not.

Parameters

fork_name	The swap name to recognize this memory region.
fork_name_len	length of fork name.
data	the data packet length.

Returns

Whether the swap was fetched to disk, or not.

Write()

BOOL Kernel::DiskSwapInterface::Write	(	const Char *	fork_name,
		SizeT	fork_name_len,
		SWAP_DISK_HEADER *	data )

Write memory chunk onto disk.

Parameters

name	The swap name to recognize this memory region.
name_len	length of fork name.
data	the data packet.

Returns

Whether the swap was written to disk, or not.

Parameters

fork_name	The swap name to recognize this memory region.
fork_name_len	length of fork name.
data	the data packet.

Returns

Whether the swap was written to disk, or not.
