single call of inflate), the parameter flush should be set to Z_FINISH. In
this case all pending input is processed and all pending output is flushed;
avail_out must be large enough to hold all the uncompressed data. (The size
of the uncompressed data may have been saved by the compressor for this
purpose.) The next operation on this stream must be inflateEnd to deallocate
the decompression state. The use of Z_FINISH is not required to perform an
inflation in one step. However it may be used to inform inflate that a
faster approach can be used for the single inflate() call. Z_FINISH also
informs inflate to not maintain a sliding window if the stream completes,

enough output space is provided, then a sliding window will be allocated and
inflate() can be called again to continue the operation as if Z_NO_FLUSH had
been used.
In this implementation, inflate() always flushes as much output as
possible to the output buffer, and always uses the faster approach on the
