Call to close an open DECOMPRESSOR_HANDLE.
Compress

Takes a block of information and compresses it.
CreateCompressor

Generates a new COMPRESSOR_HANDLE.
CreateDecompressor

Generates a new DECOMPRESSOR_HANDLE.
Decompress

Takes a block of compressed information and decompresses it.
QueryCompressorInformation

Queries a compressor for information for a particular compression algorithm.
QueryDecompressorInformation

Use this function to query information about a particular compression algorithm.
ResetCompressor

Prepares the compressor for the compression of a new stream.
ResetDecompressor
