- Compresses 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 at least 0.1% larger than
- sourceLen plus 8 bytes. Upon exit, destLen is the actual size of the
- compressed buffer.
- This function can be used to compress a whole file at once if the
- input file is mmap'ed.
- compress 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.
