-/* ===========================================================================
-     Decompresses the source buffer into the destination buffer.  *sourceLen is
-   the byte length of the source buffer. Upon entry, *destLen is the total size
-   of the destination buffer, which must be large enough to hold the entire
-   uncompressed data. (The size of the uncompressed data must have been saved
-   previously by the compressor and transmitted to the decompressor by some
-   mechanism outside the scope of this compression library.) Upon exit,
-   *destLen is the size of the decompressed data and *sourceLen is the number
-   of source bytes consumed. Upon return, source + *sourceLen points to the
-   first unused input byte.
-
-     uncompress returns Z_OK if success, Z_MEM_ERROR if there was not enough
-   memory, Z_BUF_ERROR if there was not enough room in the output buffer, or
-   Z_DATA_ERROR if the input data was corrupted, including if the input data is
-   an incomplete zlib stream.
