Data compression library

Description

PKWARE data compression library (DCL).

PKWARE DCL ("explode") ("PKWARE data compression library") decompressor used in engines:

• AGOS (exclusively for Simon 2 setup.shr file)
• Mohawk
• Neverhood
• SCI
• MADS (exclusively for the Rex Nebular installer)

Functions
bool	Common::decompressDCL (ReadStream *sourceStream, byte *dest, uint32 packedSize, uint32 unpackedSize)
SeekableReadStream *	Common::decompressDCL (SeekableReadStream *sourceStream, uint32 packedSize, uint32 unpackedSize)
SeekableReadStream *	Common::decompressDCL (SeekableReadStream *sourceStream)

Function Documentation

decompressDCL() [1/3]

bool Common::decompressDCL	(	ReadStream *	sourceStream,
		byte *	dest,
		uint32	packedSize,
		uint32	unpackedSize
	)

Decompress a PKWARE DCL compressed stream.

Returns

Returns true if successful.

decompressDCL() [2/3]

SeekableReadStream* Common::decompressDCL	(	SeekableReadStream *	sourceStream,
		uint32	packedSize,
		uint32	unpackedSize
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Decompress a PKWARE DCL compressed stream.

Returns

Returns a valid pointer if successful or 0 otherwise.

decompressDCL() [3/3]

SeekableReadStream* Common::decompressDCL

(

SeekableReadStream *

sourceStream

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Decompress a PKWARE DCL compressed stream.

This method is meant for cases, where the unpacked size is not known.

Returns

Returns a valid pointer if successful or 0 otherwise.
