- Performs one or both of the following actions:
-
- - Decompress more input starting at next_in and update next_in and avail_in
- accordingly. If not all input can be processed (because there is not
- enough room in the output buffer), next_in is updated and processing
- will resume at this point for the next call of inflate().
-
- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. inflate() always provides as much output as possible
- (until there is no more input data or no more space in the output buffer).
-
- Before the call of inflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming
- more output, and updating the next_* and avail_* values accordingly.
- The application can consume the uncompressed output when it wants, for
- example when the output buffer is full (avail_out == 0), or after each
- call of inflate().
-
- If the parameter flush is set to Z_PARTIAL_FLUSH or Z_PACKET_FLUSH,
- inflate flushes as much output as possible to the output buffer. The
- flushing behavior of inflate is not specified for values of the flush
- parameter other than Z_PARTIAL_FLUSH, Z_PACKET_FLUSH or Z_FINISH, but the
- current implementation actually flushes as much output as possible
- anyway. For Z_PACKET_FLUSH, inflate checks that once all the input data
- has been consumed, it is expecting to see the length field of a stored
- block; if not, it returns Z_DATA_ERROR.
-
- inflate() should normally be called until it returns Z_STREAM_END or an
- error. However if all decompression is to be performed in a single step
- (a 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 never required, but can be used to inform inflate that a faster routine
- may be used for the single inflate() call.
-
- inflate() returns Z_OK if some progress has been made (more input
- processed or more output produced), Z_STREAM_END if the end of the
- compressed data has been reached and all uncompressed output has been
- produced, Z_DATA_ERROR if the input data was corrupted, Z_STREAM_ERROR if
- the stream structure was inconsistent (for example if next_in or next_out
- was NULL), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR if no
- progress is possible or if there was not enough room in the output buffer
- when Z_FINISH is used. In the Z_DATA_ERROR case, the application may then
- call inflateSync to look for a good compression block. */

- The windowBits parameter is the base two logarithm of the maximum window
- size (the size of the history buffer). It should be in the range 8..15 for
- this version of the library (the value 16 will be allowed soon). The
- default value is 15 if inflateInit is used instead. If a compressed stream
- with a larger window size is given as input, inflate() will return with
- the error code Z_DATA_ERROR instead of trying to allocate a larger window.
-
- If next_out is not null, the library will use this buffer for the history
- buffer; the buffer must either be large enough to hold the entire output
- data, or have at least 1<<windowBits bytes. If next_out is null, the
- library will allocate its own buffer (and leave next_out null). next_in
- need not be provided here but must be provided by the application for the
