Constructor Details

#initialize(*args) ⇒ LZMAStream

This method does basicly the same thing as the LZMA_STREAM_INIT macro of liblzma. Creates a new LZMAStream that has been initialized for usage. If any argument is passed, it is assumed to be a FFI::Pointer to a lzma_stream structure and that structure is wrapped.
