Thanks for the information.
I have tried to create a ziptest code with the information found but 
when I tried to inflate the contents by calling inflate() [line68], I am 
getting Z_DATA_ERROR citing  input data is corrupted or not conforming 
to zlib format but I can do zipinfo or unzip on the attached ziptest.zip 
file successfully (and also the zip header is found to be valid by the 
header validity check done in the program)
Can anyone point me as to what should I being more to get rid of this 
problem?

Thanks in advance
