// DESCRIPTION
|
||
|
|
//
|
||
|
|
// The Greenleaf Compressor has a compression level member that
|
||
|
|
// dictates how much memory the compressor will devote to its
|
||
|
|
// job. The more memory, the better compression you get. The number
|
||
|
|
// returned here will normally be between AL_GREENLEAF_LEVEL_0 and
|
||
|
|
// AL_GREENLEAF_LEVEL_4. A value of AL_GREENLEAF_COPY can also be
|
||
|
|
// used, which gives no compressino at all.
|
||
|
|
//
|
||
|
|
// This is a real simple function, so it will normally be implemented as
|
||
|
|
// an inline function. The rest of the supported languages don't have
|
||
|
|
// this luxury.
|
||
|
|
//
|
||
|
|
// RETURNS
|
||
|
|
//
|
||
|
|
// A short integer that contains the current compression level for the
|
||
|
|
// Greenleaf Engine. If a compression pass fails because a file is

|
|
// The Greenleaf Compressor has a compression level member that
|
||
|

// dictates how much memory the compressor will devote to its

|
||
|
|
// used, which gives no compressino at all.
|
||
|
|
//
|
||
|
|
// When you create a decompressor, you need to match up the compression
|
||
|
|
// level in the decompressor with the level that the compressor used to
|
||
|
|
// create the data. In ArchiveLib, this is done automatically for all
|
||
|
|
// Archiving functions, as well as the Compressed object. If you are
|
||
|
|
// performing raw compression on blocks of data, you will need to ensure
|
||
|
|
// manually that the two levels are the same when creating the engine.
|
||
|
|
//
|
||
|
|
// This is a real simple function, so it will normally be implemented as
|
||
|
|
// an inline function. The rest of the supported languages don't have
