zlib.Uncompress

Method Signature

 Protected Function Uncompress(Data As MemoryBlock, ExpandedSize As Integer = -1, DataSize As Integer = -1) As MemoryBlock

Parameters

Name	Type	Comment
Data	MemoryBlock	The data to be decompressed
ExpandedSize	Integer	Optional. If specified, the decompressed size of Data in bytes.
DataSize	Integer	Optional. If specified, the actual size of Data in bytes. Specify this parameter if Data.Size=-1

Return value

The decompressed data.

Notes

Decompresses the passed MemoryBlock.

If the decompressed size is known it may be passed as ExpandedSize. If ExpandedSize is not set then the decompression operation will be repeated with progressively larger output buffers until it succeeds.

If Data.Size is -1 (e.g. converted from a Ptr) then you must specify the size as DataSize or the operation will fail.
