OK thanks for the response. Upon closer investigation, I found that it is my own problem. The LZO_COMPRESS is taking the parameters as (source, source_len, dst, dest_len) whereas zlib compress is (dest, dest_len, source, source_len). Therefore I just turned them around. It is now working !!! My next question is whether anyone has a comparison of LZO and zlib in terms of relative time taken to compress. In addition, the zlib compress2() has a compression level parameter, I would also need to know how it fairs comparing with compress(). Thanks once again.
