Thank you very much reborg.
I am going to follow whatever approach you suggested. I have a small concern here. In future, if some one comes and adds one more printf to the program (for debugging purpose), the script won't function properly right??

Is it possible to write the output values to a common memory which can be used by Unix shell as well as C program. Once the C program writes the output to that common memory , can Unix pick the values?
Since the program deals with passwords I can't write the output to a temp text file so that shell script reads the file and delete it.

How about writing the values to environment variables from C and accessing from Unix?

Iam new to Unix and C, please correct me if my questions are dumb.

Thanks
Rao.
