Function deflateEnd Copy item path

Deallocates all dynamically allocated data structures for this stream.

This function discards any unprocessed input and does not flush any pending output.

§Returns

• Z_OK if success
• Z_STREAM_ERROR if the stream state was inconsistent
• Z_DATA_ERROR if the stream was freed prematurely (some input or output was discarded)

In the error case, strm.msg may be set but then points to a static string (which must not be deallocated).

§Safety

• Either
  • strm is NULL
  • strm satisfies the requirements of &mut *strm and was initialized with deflateInit_ or similar
