	strm provides the memory allocation functions and window buffer on input,
	and provides information on the unused input on return. For Z_DATA_ERROR
	returns, strm will also provide an error message.

	in() and out() are the call-back input and output functions. When
	inflateBack() needs more input, it calls in(). When inflateBack() has
	filled the window with output, or when it completes with data in the
	window, it calls out() to write out the data. The application must not
	change the provided input until in() is called again or inflateBack()
	returns. The application must not change the window/output buffer until
	inflateBack() returns.

	in() and out() are called with a descriptor parameter provided in the
	inflateBack() call. This parameter can be a structure that provides the
	information required to do the read or write, as well as accumulated
	information on the input and output such as totals and check values.

	in() should return zero on failure. out() should return non-zero on
	failure. If either in() or out() fails, than inflateBack() returns a
	Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
	was in() or out() that caused in the error. Otherwise, inflateBack()
	returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
	error, or Z_MEM_ERROR if it could not allocate memory for the state.
	inflateBack() can also return Z_STREAM_ERROR if the input parameters
	are not correct, i.e. strm is Z_NULL or the state was not initialized.
