Re: Help please!!

I doubt if the exit() status is same as return value. This prompts me to post
this question on the list.

Consider a program whose normal return value is expected to be, say 1.
The exit status will be 0 indicating that the program terminated normally.
These two differ. Please correct me if I'm wrong.

Your answer that the shell var $? may be the right answer for my question.
Any more thoughts on the same?
