- 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 actual size of the compressed buffer.
- This function can be used to decompress a whole file at once if the
- input file is mmap'ed.
-
- 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.
