- 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.
