NTSTATUS RtlDecompressBufferLZNT1( OUT PUCHAR UncompressedBuffer, IN ULONG UncompressedBufferSize, IN PUCHAR CompressedBuffer, IN ULONG CompressedBufferSize, OUT PULONG FinalUncompressedSize ); Routine Description: This routine takes as input a compressed buffer and produces its uncompressed equivalent provided the uncompressed data fits within the specified destination buffer. An output variable indicates the number of bytes used to store the uncompressed data. Arguments: UncompressedBuffer - Supplies a pointer to where the uncompressed data is to be stored. UncompressedBufferSize - Supplies the size, in bytes, of the uncompressed buffer. CompressedBuffer - Supplies a pointer to the compressed data. CompressedBufferSize - Supplies the size, in bytes, of the compressed buffer. FinalUncompressedSize - Receives the number of bytes needed in the uncompressed buffer to store the uncompressed data. Return Value: STATUS_SUCCESS - the decompression worked without a hitch. STATUS_BAD_COMPRESSION_BUFFER - the input compressed buffer is ill-formed.
